i do, i have felt the presence of the ghost of my dead grandpa, i have once woken up in the middle of the night to be staring at glowing yellow eyes, i think myself (because of my maturity and mental copasity and mental quirks) i may be superhuman to an extent. not to mention the sounds i used to always hear in the attic all the time. so anda don't have to agree with me but i think i have a good reason for believing in these kinds of things.
I believe in the supernatural, but only to some extent, for example, i believe in the Ouija board and refuse to play, entitys, and i do believe that if someone has unfinished business when they die they still linger on in reality.
But as far as '' ghosts and poltergeist's '' go and all that '' being haunted '' nonsense, Not At All.
