How long does sleep paralysis last. Sleep paralysis is a kind of paralysis which makes a person incapable to move for a while after wakening up from sleep or onset sleep. This problem does not remain for long, but lasts in few minutes. While Schizophrenia is also a sleep disorder, but it creates sleeping problems.
REM sleep is an active mind inside a paralyzed body, while nREM sleep is a resting mind inside a functioning body. This is why sleepwalking is possible during nREM sleep and not during REM sleep: your body is paralyzed during REM sleep but not in nREM. As for why sleepwalking occurs... well, we still don't really know. See Wikipedia: Sleepwalking for much of the current knowledge.
