DREAMING AS DELIRIUM - A MENTAL STATUS ANALYSIS OF OUR NIGHTLY MADNESS

Dreaming is characterized by formal visual imagery (akin to hallucinat ion), by inconstancy of time, place, and person (akin to disorientatio n), by a scenario-like knitting together of disparate elements (akin t o confabulation), and by an inability to recall (akin to amnesia). Tak en together, these four dream features are similar to the delirium of organic brain disease. By studying the brain during rapid-eye-movement (REM) sleep-the phase of sleep in which most dreaming occurs-we can b egin to understand its basis in the altered neurophysiology of REM.
