Sleepwalking and Night Terrors

Sleepwalking, night terrors and REM disorder are all parasomnia's that involve involuntary movement. The brain is in a strange half-awake half-a-seat state when people sleepwalk. A person will get up and be convinced of some sort of delusional event that's going on around them but they're awake enough to navigate the house. People have been known to drive their car, drive a motorbike,. which blows my mind.
