No I dont belive in ghosts. I have heard many stories of people who have seen them, but I havent so I dont belive they exist.
I believe in the saying "To see is to believe". Since I haven't seen a ghost in my long years of existence on earth, therefore, I don't believe on it.
I won't say that I believe in ghosts, but still I cant go to the places alone where there is too much dark. something scares me. yet I don't know what is the reason behind this.
