Do you believe in the paranormal? If so, you might not be surprised to hear of alien abductions, brushes with ghosts, or even imps and ghouls invading one's bedroom at night. It's certainly entertaining to believe in such otherworldly events. But the phenomenon of sleep paralysis might just provide a more viable explanation to these occurrences than traditional paranormal explanations. REM sleep is a deep cycle of sleep in which we have our most vivid dreams. At this stage, we are paralyzed. This might simply be a sort of safety device to stop us from acting out our dreams so that we don't, for example, attempt to fly. But during sleep paralysis, features of REM sleep continue even after we wake up. At this stage, we are paralyzed. As much as 8% of the population experiences this phenomenon, perhaps explaining many events that might otherwise be attributed to paranormal activity.
