We've all felt the uneasy, spine-tingling feeling that someone or something is watching us - be it an intruder, a ghost, or something far more sinister. And the truth is, scientific explanations for ghosts really don't mean much when you're overcome with that creepy-as-heck feeling in the middle of the night. All the logic in the world couldn't disprove what you already know: your house is probably haunted and some sage or holy water isn't going to cut it.
On the other hand, most of the time there really is a normal, logical explanation behind seemingly paranormal experiences. Even an apparent demonic possession can be explained pretty soundly with science (sorry, Lucifer). There's a real science behind haunted houses, and the reason our bodies sometimes feel on edge is usually kind of anticlimactic. Listen, no one is trying to tell you to buy property on top of an Indian burial ground anytime soon, but before you pack up all your belongings and move out of your haunted mansion in the middle of the night, you should really consider a couple of facts.
These scientific explanations for haunted houses may ease your mind, but you should probably still burn your Ouija board just in case.
