Well i have always wondered why some people see ghosts and others dont and finaly after talking to enough people i came up with a theory but this theory is easier to belive if you belive you have an old soul(you belive you lived before you where born)If you where murdered in your old life you will see the ghosts of people that were murdered therefore you will see whailing screaming screaching ghost this also happens if you murdered some1 in a past life. if you died peacefully you will just see ghosts walking around being themselves.
