                                            Sleep paralysis is commonly associated with panicky feelings and fearful imagery or some supernatural, otherworldly event involving ghosts, monsters, or extraterrestrials. 
Sleep paralysis may include fear-inducing hallucinations that make the experience seem supernatural or threatening. These may be in the form of sounds, sights, scents, or feelings. 
During deep REM sleep, there is a brief period where the body loses muscle control to prevent the acting out of dreams. This period typically ends before the person wakes, so they are never aware of their inability to move. 
However, this isn’t always the case. When the person wakes abruptly, there may be a disconnect between fully waking up and the end of REM sleep, resulting in the mixed state of consciousness we call sleep paralysis.
People with obstructive sleep apnea experience this phenomenon at higher rates than those without.
