No. but i know they are real. If te believe them, it gives them power and te are più likely to be haunted. Also if te are scared of them it gives them power. You're più likely to have ghosts near te if te are scared of them o 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...
