The Creepy Scientific Explanation Behind Ghost Sightings

Since scientists love nothing more than inducing feelings of fear and terror in unsuspecting citizens, most of the concert goers had no idea what was going on. As a result one minute they were enjoying some sweet tunes while the next a feeling of dread invaded their hearts, crushing all hope and happiness. At the end of the experiment approximately 22 percent of the people involved in the experiment reported feelings of unexplainable dread, chills and depression when infrasound was blasted into the crowd.

Why would it have this effect? It may be evolution. It doesn't take a mad scientist mind control device to create infrasound -- mother nature is creating this type of low frequency vibration all the time. Volcanos, earthquakes, strong ocean waves and even winds hitting the hillside in just the right spot can create infrasound. Even animals can create it, and tigers are particularly well known as a source. The frequency of a tiger's roar is around 18Hz -- right in that range we mentioned earlier.

All of the things that create the sound are huge, powerful and dangerous. Evolution might have taught us that this sound means Bad News.
