00:00You have almost certainly seen a ghost.
00:02You just didn't realize it.
00:05Here is the crazy fact about apparitions.
00:08Scientists can literally make you see one.
00:11It's called the sensed presence effect.
00:14When your body is exhausted, stressed, or alone in a quiet room,
00:19your brain gets confused about where your body ends.
00:22So it creates another person right behind you.
00:27That's why almost every ghost sighting is the same.
00:30A figure in the corner of your eye.
00:32A feeling that someone is watching you.
00:34A shadow in the doorway.
00:36It's not a spirit.
00:38It's your own brain, projected outward.
00:41And the creepiest part?
00:43It happens most often at around 3 a.m.
00:46Not because ghosts are more active,
00:48but because that's when your body temperature and willpower are at their absolute lowest.
00:54So that apparition you saw wasn't visiting you.
00:58It was you.
