It Does Exist
I believe in the super natural. There is no way to disprove it. All you need is a terrible event, and the supernatural might show up. I get terrified everytime I enter a hotel room or a bathroom. Sometimes, the unexpected shows when you least expect it.
The supernatural might be nice. They may not haunt you, but help you. I recall a story about a boy who warns people about disasters before it happens. The ghost is friendly, and wouldn't hurt anyone emotionally or physically.
However, there are ghosts who haunt people. In an motel, people recorded strange occurances that were frighting. Whenever someone enters a room, their hands becomes cold. Suddenly, their bodies becomes stiff and unmovable. The ghost will show its face, and people will get scared.
