Sleep paralysis is a condition in which an individual remains unable to move after waking. Sleep paralysis commonly occurs during REM sleep, the state in which people most often dream.

In other scenarios, the suggestibility of the human mind can create feelings and sensations that are often attributed to a haunting or ghost encounter.Learn more about Superstition
