Sleep is purely and simply a series of repair and test sequences
throughout the night. No magic,no reinforcement of learning. The REM
sequences are
hallucinations while the brain is in a certifiably insane chemical
state.Like J. Allan Hobson states on page 77 of his book THE CHEMISTRY
OF CONSCIOUS STATES:" dreaming is not like a psychosis, it is a
psychosis.It's just a healthy one,"Why anyone pays any attention at
all to the insane psychotic stateREM sleep, and which Nature programs
us to forget is beyond me. It seems there are still people who have
read Freud and can't shake some of his absurdities.
