Ghosts

Despite my religious beliefs, many are surprised to learn of my incredible skepticism of ghosts and other paranormal entities. Some of my skepticism is informed by my religious beliefs, but most comes from learning about haunted houses being scams from historical societies. I do believe in the possibility of angels and demons, but I would tend to believe in more practical explanations than supernatural ones. With that said, I wouldn't decry a seemingly miraculous event as being assisted by angels even if supernatural intervention wouldn't be necessary. However, demon possessions I would consider to be preternatural where clearly something extraordinary is happening, but I wouldn't rule out mental illness very quickly. Granted, I have never witnessed an alleged demon possession, so I can't say that with absolute certainty. The reason why I could believe in angels and demon versus ghosts is simply because I don't see biblical evidence for it, but as I said, my stronger case is with the prevailing evidence that a lot of hauntings are fake or exaggerated.

One of the more interesting theories behind ghosts and other paranormal events is that they may be caused by something called infrasound. Sounds below 20 Hz which is below the human hearing range is infrasound. Humans may not be able to hear it, but sounds with a frequency of 19 Hz have been experimentally shown to produce weird effects on humans. This may have something to do with the resonant frequency of the human eye being 18 Hz. Infrasounds can be produced by old motors like in ceiling fans, pipes, and storms. That ominous feeling in your stomach when a storm is incoming may be from infrasound.

From the James Bond Skyfall trailer

The closest paranormal experience I've had was fairly recently. I was accessing the supply closet at work. All of the sudden the projector screen automatically came down and flashed the image to the right at me. This really spooked me quite considerably. Accidentally bumping into the control panel and activating the projector is down right impossible. Heck, just trying to purposely activate the projector is hard enough. Granting that, the unlikelihood that a trailer for a movie that came out two years ago would happen to be playing and playing this particular scene is just unsettling. I'm not sure what sins I should be thinking on, but needless to say it definitely gave me pause. Not evidence of a ghost, but it is funny that my coworkers would always complain about a ghost setting off the toilet's automatic flusher.
