I've always been interested in ghosts and the paranormal. And from everything I've gathered (television basically-_-) here is a quick rundown of things half of me believes:
=Ghosts can haunt/possess/hook into people, places, and objects. But only one of the three.
=Psychic echoes are not spirits they are different.
=A dead person becomes a ghost if they refuse to go through a mysterious smoky tunnel after death
=Immediately after death a soul can hang around the living world for a bit but eventually they most go 'into the light' or risk being stuck on Earth
=People that commit suicide are more likely to become ghosts.
I don't know shit I'm talking out of my ass, but half of me believes it!
