Finally, 31.7% of the lab incorporation dreams included relative projections into a near future (e.g., the experiment having been completed), but very few projections into the past (2.6%). Common themes associated with lab incorporation were: Meta-dreaming, including lucid dreams and false awakenings (40.7%), Sensory incorporations (27%), Wayfinding to, from or within the lab (24.3%), Sleep as performance (19.6%), Friends/Family in the lab (15.9%) and Being an object of observation (12.2%). They tended to be related to higher depression scores, but not to sex, nightmare-proneness or anxiety. Lab incorporations occurred in over a third (35.8%) of all dreams and were especially likely to occur in REM sleep (44.2%) or from morning naps (48.4%). Here we assessed 528 dreams (N = 343 participants) collected in a Montreal sleep lab to 1) evaluate state and trait factors related to such dreams, and 2) investigate the phenomenology of lab incorporations using a new scoring system. However, as common as such dreams are, they have rarely been given a thorough quantitative or qualitative treatment. The content of such dreams draws upon episodic memory fragments of the participant’s lab experience, generally, experimenters, electrodes, the lab setting, and experimental tasks.

Requests must come via the owner of the database who holds ethical approval for the data in question. Please note that our ERB does not allow external researchers to contact them directly for data requests.

However, anonymized results extracted from the dream reports will be made available upon request to the owner of the database (currently Director of the Dream & Nightmare Lab: Tore Nielsen) for researchers who meet our Ethics Review Board’s (ERB) criteria for access to confidential data. The data may contain identifiable information. Source records (dream reports) cannot be shared publicly due to restrictions imposed by the Research Ethics Board of the CIUSSS du Nord-de-l'Île-de-Montréal.
