No. but i know they are real. If Du believe them, it gives them power and Du are Mehr likely to be haunted. Also if Du are scared of them it gives them power. You're Mehr likely to have ghosts near Du if Du are scared of them oder believe them. So my main moral of this answer is :
Yes I do believe in ghost I have heard them They have touched me in the night My friend took a picture of one with her phone I have so much proofs to believe in them...
