I think fake but i have been shown that ghost may exist first hand.
My friends house he says is haunted, i have never seen anything of the sort..BUT, we had just gotten home from eating out. His ex Girlfriend at the time went upstairs, we poped open a beer. We hear this loud bang(something fell or she dropped something we assume) and we ask if she is ok, she does not answer. 15 seconds later she walks down the stairs, and i have never seen anyone as white as she was, ever. Tears pouring down her face. She could hardly speak, she said she saw a dark haird figure standing in the hallway
A year later and new girlfriend, she says she saw a dark haird figure in the same area as previously stated by his ex.
Take it as you will but, hey do we or will we ever know.
