This past week I have been having frequent cases of sleep paralysis.
For those who do not know, sleep paralysis is when the brain awakens from REM sleep but the body remains “asleep” (in paralysis). Sort of the reverse of sleep walking, which is when the body is ‘awake’ but the brain is asleep.
In short, you are fully conscious but unable to move. This can last a few seconds or a few minutes. However, eye movements are still possible. Individuals experiencing this often feel extreme panic as they try to reestablish the connection between mind and body.
