Both eerie and haunting, this photography series REM, by Florian Mueller, explores our state of mind when experiencing rapid eye movement sleep. This is the unique phase of mammalian sleep characterised by random movement of the eyes, low muscle tone throughout the body, and the propensity of the sleeper to dream vividly.
Mueller explains: “Exploring dreams has always fascinated me. Especially the dreams in which one has the guess that it could be a dream, but is not sure. Just this feeling that something is wrong. Like here: the environment is not uncommon, there is no foreign body present, but something is wrong.
