One of Merriam-Webster’s definitions for the word “ghost” is “a disembodied soul of the dead.” However, these spirits have long been spotted before any formal definition was set. Sumerians, Ancient Greeks, and Ancient Egyptians were very familiar with the shades of expired loved ones coming back for one reason or another. Despite each new scientific reasoning behind ghostly experiences, there’s a large portion of today’s population that maintains hauntings are real. Hell, traipse through the internet long enough and you’ll find one paranormal video after another. Whether or not you believe in their veracity, plenty of them are still damn creepy.
Many well-respected luminaries have professed their belief in spirits. One of the more famous ones was Sir Arthur Conan Doyle—author of the “Sherlock Holmes” stories—whose belief in the spirit realm was so strong he actually sought to prove the existence of ectoplasm, a gelatin-like substance left behind by paranormal guests.
Sure, there’s been no solid scientific findings that prove ghosts are real; but then again, there’s not a solid way of truly disputing their existence either. When you think about it that way, the theory of ghosts is hanging in scientific limbo. But here’s a little food for thought next time you’re checking out some supposedly haunted site: disbelievers almost always die in horror movies.
The whole point of science is that it’s based in fact, and the fact that no ghosts have been evidenced by science proves they don’t exist. If we’re going off of belief only, the Merriam-Webster definition shows the existence of ghosts is contingent upon whether or not someone believes in souls in the first place. There are even some “renowned skeptics” who make it their mission to ensure all paranormal activity is proven false.
Plenty of the so-called “uncanny” occurrences associated with ghosts have been debunked. For example, that “feeling like you’re being watched” is actually caused by infrasound, a sound which can't be heard by the human ear that causes unsettling sensations. Infrasound can even effect vision, causing ghostlike hallucinations.
Everything has an explanation eventually. Granted, there are plenty of solid reasonings behind most ghost sightings, but one that completely usurps the belief is bound to pop up sooner or later. More likely than not, that “ghost” is probably some disgruntled old man getting ready to call you a “meddling kid.”
