Current Biology · Experimental study
Four laboratory groups explored whether people in verified REM sleep could answer an experimenter’s questions using eye movements or facial-muscle signals.
Method
Thirty-six people took part. Correct answers were recorded on 29 occasions across six participants.
What to keep in mind
Successful communication occurred in a subset of participants. This work concerns responses to ordinary sensory questions during sleep, not telepathy or remote viewing.
