CAS Effects of spatial smoothing on functional brain networks. Furthermore, the groups were distinguished based on a median split on scores to a composite measure that also included elements that may have varied with dream recall frequency, making it unclear whether the results could have been partly influenced by differences in dream recall. Now we use only handwritten algorithms to overcome the problem, but we're going to use machine learning and AI to improve Remmyo decoding.. Indeed, lucid dreams can range from a realization about the fact that one is dreaming followed by a loss of lucidity shortly thereafter to more extended lucid dreams in which an individual can maintain lucidity for prolonged periods of time63. Google Scholar. For his initial experiment, Raduga used the sleep laboratory of the Neurological Clinic of Frankfurt University in Germany. was supported by the National Institutes of Health under Ruth L. Kirschstein National Research Service Award F32NS089348 from the NINDS. The scientific evidence for lucid dreaming normally starts with the ingenious work of Keith Hearne, Ph.D. at the University of Hull (UK) in 1975 and Stephen LaBerge, PhD at Stanford University in 1978. . Unintentionally, people strain more than one muscle, and EMG sensors detect it all. Google Scholar. Lucid dreaming becomes more likely during the nap. The bottoms and tops of the boxes show the 25th and 75th percentiles (the lower and upper quartiles), respectively; the inner white band shows the median; and the whiskers show the most extreme data points not considered outliers (outliers are plotted separately with red squares). An extended discussion of this issue is beyond the scope of the present article; however, overall these remarks emphasize the need for the development of standardized measures that can be used to assess individual differences in frequency of lucid dreams that simultaneously measure the duration and degree of lucidity during dreams. Holzinger, B., LaBerge, S. & Levitan, L. Psychophysiological correlates of lucid dreaming. There are established methods for the objective validation of individual lucid dreams in a sleep laboratory setting using volitional eye-movement signals4, but there are no protocols for physiologically validating the frequency of lucid dreams. Westfall, P. H. On using the bootstrap for multiple comparisons. 106, 11251165 (2011). Participants completed a questionnaire that measured their dream recall and lucid dreaming frequency (Supplementary Methods: Dream and lucid dream frequency questionnaire). Group-level analysis was conducted using the general linear model (GLM) framework implemented in SPM12 (Wellcome Trust Department of Imaging Neuroscience, University College London, UK). All rights reserved. Finally, we evaluated several additional cognitive variables which have been hypothesized to be associated with lucid dreaming and have been linked to PFC function, including working memory capacity, trait mindfulness and prospective memory (e.g., refs.2,33,34), in order to test for between-group differences and, if necessary, to be able to control for these variables in our MRI analysis. Key points. 15, 125 (2002). Given that dissociation (i.e. 14, 88100 (2010). What if we learned to use sleep dreaming to practice goal attainment, heal the body and mind, and explore subconscious messages? (MIT Press, 1999). Youll then be able to start practising basic dream control so that you can guide and shape the dream if you want to. J. Cogn. 7, 113140 (2011). Radugas study is the first to try to develop this sort of communication into a general language. Schaefer, A. et al. In this sense, lucidity is an aspect of dreams that can be triggered using different means. Once you get lucid, calmly remind yourself of your goal: I want to practise walking on my hands in a dream, or: I want to go on a romantic date with X. Finally, patients with damage to this region frequently display metacognitive deficits such as an inability to monitor disease symptoms or accurately appraise their cognitive functioning25,26, similar to the lack of metacognitive insight into the global state of consciousness characteristic of non-lucid REM sleep dreams27. Windt, J. M. & Metzinger, T. The philosophy of dreaming and self-consciousness: What happens to the experiential subject during the dream state? LaBerge, S., Baird, B.

Smooth tracking of visual targets distinguishes lucid REM sleep dreaming and waking perception from imagination. "A lucid dream is defined as a dream during which dreamers, while dreaming, are aware they are dreaming," specialists explain. Neuron 72, 665678 (2011). Finally, timeseries data were temporally filtered (high-pass=0.01Hz, low-pass=0.1Hz). Caspers, S. et al. lucid dreaming, phenomenon of sleep in which one is aware that one is dreaming. - May 9, 2023 9:42 pm UTC. However, a limitation of the study was a lack of specific assessment of lucid dream frequency in the high lucidity and low lucidity groups (lucid dream frequency for the two groups was not reported). collected data; B.B. A 2021 study by Northwestern University found that people having especially realistic dreams (and sometimes lucid dreams) were able to communicate with researchers who were awake through eye and muscle movements. Cytoarchitectonic identification and probabilistic mapping of two distinct areas within the anterior ventral bank of the human intraparietal sulcus. & LaBerge, S. Conscious mind, sleeping brain: Perspectives on lucid dreaming (Plenum Press, 1988). Consistent with this, a functional magnetic resonance imaging (fMRI) case study found increased BOLD signal in many of these same regions during lucid compared to non-lucid REM sleep, including the anterior prefrontal cortex (aPFC), bilateral inferior parietal lobule (IPL), precuneus and inferior/middle temporal gyrus (ITG/MTG)9. While we did not find evidence in support of a relationship between these variables and spontaneous frequent lucid dreams, it is worth noting that the relation between lucid dreaming and working memory has been discussed primarily in the context of successfully being able to activate the pre-sleep intention to recognize that one is dreaming during a dream2, and the relation to prospective memory is mostly considered in the context of learning to have lucid dreams by remembering to recognize that one is dreaming. Article To the best of our knowledge, the current study is the first to evaluate differences in brain structure and functional connectivity of individuals who experience lucid dreams with high frequency. NeuroImage 16, S497 (2002). During lucid dreaming, however, the physiology of the brain changes such that dreamers realize that they are in fact dreaming. Compared to controls, the frequent lucid dream group showed significantly increased resting-state functional connectivity between left aPFC and bilateral angular gyrus, bilateral middle temporal gyrus and right inferior frontal gyrus, and higher node degree and strength in left aPFC.

Learn how to avoid sleep paralysis, achieve REM sleep, interpret dreams & much more! Cogn. As noted in the introduction, a limitation of that study is that the high-lucidity group was not a sample of frequent lucid dreamers, but rather individuals from a database that scored above the group median on a composite measure of dreaming, which measured not only frequency of lucid dreams but also different dimensions of dream content. Foster, J. L. et al. Uddin, L. Q. et al. No differences in betweenness centrality or eigenvector centrality were observed between groups for any node (all p>0.05, two-tailed independent samples t-test, max t corrected).

Segmentation and surface reconstruction. Sleep 35, 10171020 (2012). While we tend to focus on our waking life, roughly one-third of our lives is spent in the dream world. It depends on many factors, and varies a lot from person to person. & Liu, T. T. A component based noise correction method (CompCor) for BOLD and perfusion based fMRI. Mean connectivity values from each binarized mask were exacted using the MarsBar toolbox96. In order to ensure that the spheres were contained within the pial surface of the cortex, spheres were shifted by two voxels in the x and y dimensions yielding a final MNI coordinate of x=24, y=64, z=10. However, overall EEG studies of lucid dreaming show considerable discrepancies and at the current time these results should be interpreted cautiously given methodological issues such as low statistical power19,20.

All network metrics were computed in Matlab v 9.1 (The MathWorks Inc., Natick, MA, 2008) using the Brain Connectivity Toolbox98. The cluster peak for left parietal cortex was also in PGa and the overlap between the functional cluster and the cytoarchitectonic maps was 34.3% for PGa, 19.7% for PGp, 6.7% for hlP1 and 0.2% for hlP3 (Fig. Following recommended practice99, rather than apply a single threshold to graphs, which would limit any findings to a single arbitrary connection density, we thresholded graphs over a range of connection densities (0.050.35) in steps of 0.01. Power, J. D. et al. Given that frontoparietal activity is typically suppressed during REM sleep, an intriguing follow-up to these findings based on the current results would be to examine whether AChEIs, and galantamine in particular, may facilitate lucid dreaming through increasing activation within the network of fronto-temporo-parietal areas observed here. LaBerge, S. Lucid dreaming: Psychophysiological studies of consciousness during REM sleep in Sleep and Cognition (eds Bootzin, R. R. Kihlstrom, J. F. & Schacter, D.

The Curiosity factor corresponds to an an attitude of wanting to learn more about ones experiences, whereas the Decentering factor corresponds to awareness of ones experience with some distance and dis-identification rather than being carried away by ones thoughts and feelings80. Meanwhile, brain waves, heart rate, and blood pressure all become similar to the levels seen in the awake state. Binder, J. R., Desai, R. H., Graves, W. W. & Conant, L. L. Where is the semantic system? Here I share playlists of the best lucid dreaming content on YouTube. Her work has appeared on SYFY WIRE, Space.com, Live Science, Grunge, Den of Geek, and Forbidden Futures. Furthermore, mean ratings in the insight subscale increased from approximately 0.10.2 in the sham stimulation to 0.50.6 in the 25Hz or 40Hz stimulation conditions. The frequent lucid dream group also reported several additional variables related to their experiences with lucid dreaming, including the number of lucid dreams they had in the last six months, the most lucid dreams they had ever had in a six-month period, whether they had engaged in training to have lucid dreams and their general interest in the topic. Middle panel: Volume slices illustrating bilateral MTG and IFG results. The power of lucid dreaming will also greatly enhance your waking life, opening new avenues of creativity, confidence, self-improvement, problem-solving, philosophical exploration and so much. Vincent, J. L., Kahn, I., Snyder, A. Explore lucid dreaming without the nonsense. wrote the paper. In line with the above ideas, several studies have attempted to induce lucid dreams through electrical stimulation of the frontal cortex during REM sleep. PubMed Cytoarchitectonic mapping studies have shown that AG can be divided into anterior (PGa) and posterior (PGp) subdivisions and IPS can be divided into three distinct subdivisions (hlP1 on the posterior lateral bank, hlP2 which is anterior to hIP1, and hlP3 which is posterior and medial to both subdivisions)51,52. Hum. Andrews-Hanna, J. R., Saxe, R. & Yarkoni, T. Contributions of episodic retrieval and mentalizing to autobiographical thought: Evidence from functional neuroimaging, resting-state connectivity, and fMRI meta-analyses. Crone, J. S. et al. The simple definition of a lucid dream is any dream in which you realize within the dream that you're dreaming. "But communication between asleep people will become an ordinary thing., Psychology of Consciousness: Theory, Research, and Practice, 2023. In the OSpan the to-be-remembered stimuli are letters and the unrelated task is verifying the accuracy of an equation; in the SymSpan the to-be-remembered stimuli are locations of red squares in a 44 grid and the unrelated task is verifying the vertical symmetry of an image; in the RotSpan the to-be-remembered stimuli are arrows pointing in one of eight different directions and the unrelated task is whether a rotated letter is presented correctly. Wake up to the opportunities that await you in sleep, and join experts in exploring the potential of lucid dreaming. LaBerge, S. Signal-verfied lucid dreaming proves that REM sleep can support reflective consciousness. ROI timeseries were estimated by averaging voxels within each ROI. Lucid dream frequency was measured with a 15-pt scale ranging from 0 (no lucid dreams) to 15 (multiple lucid dreams per night). 785907 (Human Brain Project SGA2), and the Luminous project (EU-H2020-fetopen-ga686764). The main problem is that it is hard to use only one muscle on your face to say something in Remmyo, he said. EEG studies have also reported increased activity in the beta band over parietal regions17 or gamma band in frontal regions18 during lucid compared to baseline REM sleep. A second theory posits a psychological, rather than a physiological, mechanismnamely, that metacognition leads to lucidity. Become a patron to. In 4 out of the 5 cases that were within 1 rank value, the difference in reported dream recall frequency was between 7 dreams recalled per week and 56 dreams recalled per week, and in the remaining case the difference was between 34 dreams recalled per week and 56 dreams recalled per week. Individual differences associated with lucid dreaming in Conscious mind, sleeping brain (eds LaBerge, S. & Gackenbach, J.) NeuroImage 62, 774781 (2012). Sleep Res. Despite initial skepticism from some scientists and philosophers, lucid dreaming has been demonstrated to be objectively verifiable through volitional eye movement signals which can be recorded. What is lucid dreaming?. In brief, each task presents to-be-remembered stimuli in alternation with an unrelated processing task. In contrast, gaining lucidity during dreaming sleep involves regaining cognitive abilities associated with higher-order consciousness, including the ability to be explicitly aware of oneself and ones state55. Behzadi, Y., Restom, K., Liau, J. Remmyo consists of six sets of facial movements that can be detected by electromyography (EMG) sensors on the face. Google Scholar. 22, 821 (2013). Baird, B., Castelnovo, A., Gosseries, O. et al. In lucid dreams, you can go beyond everyday experience. For the frequent lucid dream group, we recruited individuals who reported a minimum of 34 lucid dreams per week, or approximately one lucid dream every other night without engaging in training to have lucid dreams. Sleep 32, 11911200 (2009). In The new science of dreaming: Cultural and theoretical perspectives (eds Barrett, D. & McNamara, P.) 193247 (Praeger, 2007). Imagine waking up in a dream to fly or, as described by meditation masters, when dreaming of being chased by a tiger, to instead become the tiger? This study evaluated the neuroanatomical/neurofunctional correlates of frequent lucid dreams and specifically whether functional connectivity of aPFC is associated with frequent lucid dreams. Sleep Hypnosis 5, 182187 (2003). To estimate connectivity, spherical ROIs of 6mm radius were defined in aPFC based on the peak voxel reported in Dresler et al.9 which hadincreased fMRI BOLD signal response during signal-verified lucid REM sleep dreaming. Be part of the community. Acad. By Jocelyn Timperley 13th April 2023 Lucid dreaming holds a widespread appeal, but many people simply can't do it. Another study tested whether applying transcranial alternating current stimulation (tACS) in the low gamma band (25Hz and 40Hz) to frontal regions would induce lucid dreams71. We followed up this network overlap analysis by evaluating the connectivity between all nodes within the frontoparietal control subsystem that showed the largest overlap with the functional connectivity results, based on a 400 node parcellation of the 17 functional networks36. This statistical approach has been used in previous studies and allows for strong control over type I error103,104. WIRED Media Group Cogn. PubMed Central As its name suggests, it's characterised by random rapid movement of the eyes, and is generally the . The most comprehensive and reliable list of lucid dreaming techniques online. There are a number of ways to induce lucid dreaming, including recording dreams in a diary, using drugs that inhibit neurotransmitters (signaling molecules in the brain), using external sensory cues, and interrupting sleep. CAS The sky is absolutely clear blue and the rays of the sun filter down through the outstretched feathers of the bird I feel impressed and joyous at the marvellous beauty of this scene which I savour, fully and deliberately, in every detail. Dream Res. Lucid dreams are the ability to be conscious of the fact that you are dreaming. Z., Raichle, M. E. & Buckner, R. L. Evidence for a frontoparietal control system revealed by intrinsic functional connectivity. Iglesias, J. E. et al. Lucid dreaming usually occurs in the stage of sleep called rapid eye movement, or REM sleep. Crawford, J., Smith, G., Maylor, E., Della Sala, S. & Logie, R. The Prospective and Retrospective Memory Questionnaire (PRMQ): Normative data and latent structure in a large non-clinical sample. While frequent spontaneous lucid dreams are uncommon, evidence indicates that lucid dreaming is a learnable skill that can be developed by training in strategies such as metacognitive monitoring (i.e., reality testing) and, especially, prospective memory65,66. Furthermore, inter-individual variance in metacognitive ability has also been linked to aPFC gray matter volume23,24 and aPFC functional connectivity24. Article PubMed Neurosci. The FPCN is a large-scale brain network that is interconnected with both the default mode network (DMN), which is linked to internal aspects of cognition, such as autobiographical memory43,44, spontaneous thought45,46, and self-referential processing47, and the dorsal attention network (DAN), which is involved in visuospatial perceptual attention48,49.

While there was no specialized sleep language used during this experiment, it still demonstrated they could reach out to the waking world. Region-of-interest (ROI) analysis revealed increased connectivity between left aPFC and bilateral PGa (blue outline) [all p<0.05]. Parcellation masks were transformed back to each subject EPI space using the BBRegister affine T1 to EPI transform. What could we learn about ourselves if we understood the language of dreams? For reasons not currently understood, humans are typically unaware that they are dreaming while dreaming. Differences in global mean intensity between functional sessions were removed by normalizing the mean of all voxels across each run to 100. Psychol. This can be achieved by thresholding A by the connection density (), also known as cost factor, of the network, which is the number of existing connections over the total number of possible connections100,101.

Dissociable connectivity within human angular gyrus and intraparietal sulcus: Evidence from functional and structural connectivity. I Interest in lucid dreaming - awareness of dreaming while sleeping - has been on the rise over the past decade or so, with a particularly big spike in internet searches mid-pandemic. Percept. Dale, A. M., Fischl, B. The idea of lucid dreaming involves the realization within the dream that it's, well, a dream and not reality and, for some people, the ability to change the "plot" of your dream as it unfolds. While lucid dreamers use dreamstates for a variety of purposes, such as deep meditation, problem-solving, and artistic inspiration, they universally report that the lucid dreaming experience is fun. Thus, it remains plausible that there could be a relationship between working memory and prospective memory and (successful) training in lucid dreaming despite a lack of a relationship between these variables and spontaneous frequent lucid dreams. Various theories attempt to explain the underlying mechanisms of lucid dreaming. Google Scholar. Overall this method ensured that the frequent lucid dream group and control group were closely matched on dream recall frequency.

Before you can fully explore the world of lucid dreaming, you need to know how to stay lucid instead of waking up seconds after Several additional checks were made to ensure that participants had a clear understanding of the meaning of lucid dreaming. Rev. Achard, S. & Bullmore, E. Efficiency and cost of economical brain functional networks. We found that compared to a control group matched on age, gender and dream recall frequency, individuals who reported lucid dreams spontaneously approximately every other night or more hadincreased resting-state functional connectivity between the left anterior prefrontal cortex (aPFC) and the bilateral angular gyrus (AG), bilateral middle temporal gyrus (MTG) and right inferior frontal gyrus (IFG). A fast diffeomorphic image registration algorithm. Article To compare head motion between groups, head motion was calculated by mean framewise displacement (FD) using Jenkinsons relative root mean square (RMS) algorithm84. NeuroImage 38, 95113 (2007). Lucid Dreaming also known as "conscious dreaming," also helps you uncover hidden aspects of yourself to gain a more holistic view of reality. Rev. Lucid Group ( NASDAQ: LCID) rallied 6.55% on Monday on a strong day overall for the electric vehicle sector. These same brain areas, particularly aPFC and IPL/AG, show reduced regional cerebral blood flow (rCBF)13,14,39 during REM sleep compared to waking (see ref.15 for a review). To evaluate whole-brain differences in network and topological properties, we next parcellated the brain into 1015 regions according to the Lausanne 2008 atlas37,38 and performed graph-theoretic analysis. Although aPFC connectivity was the main target of investigation in the current study, we also performed a supplementary seed-based functional connectivity analysis on other regions identified in ref. Asterisks indicate significant differences (p<0.05) between conditions with a nonparametric bootstrap test after correcting for multiple comparisons against a surrogate max t distribution across all nodes.

This result contrasts with a study that found that two regions of aPFC had increased gray matter density in a high-lucidity group compared to a low-lucidity group30. Rubinov, M. & Sporns, O. Choi, H. J. et al. Dynamic statistical parametric mapping: Combining fMRI and MEG for high-resolution imaging of cortical activity. Ann. Based on a parcellation of 17 resting-state networks in the human brain, which distinguished potentially separable FPCN networks35, a recent study found that the FPCN could be fractionated using hierarchical clustering and machine learning classification into two distinct subsystems: FPCNa, which is more strongly connected to the DMN than the DAN and is linked to introspective processes, and FPCNb, which is more strongly connected to the DAN than the DMN and is linked to regulation of perceptual attention50. Cortex 19, 27672796 (2009). We additionally evaluated average gray matter density between groups in the two regions of prefrontal cortex and bilateral hippocampus observed by ref.30 to show increases in a high lucidity group. The Air is the first model from Lucid, a startup based in California. Future studies might consider testing a wider range of stimulation parameters, particularly applied to aPFC, as well as combining stimulation with training in the appropriate attentional set for lucid dream induction. Beverly D'Urso has been a lucid dreamer since she was 7 years old. For most individuals lucid dreams spontaneously occur infrequently, however there is substantial variation inlucid dream frequency, ranging, by current estimates, from never (approximately 4050%) to monthly (approximately 20%) to a small percentage of people that experience lucid dreams several times per week or in some cases every night11,12.
