Well if you personally ask me I will say I never seen any but I do believe in Ghosts as it is written in our holy book that they exists.
Today someone known to me visit me and asked me that I ever visited Thermal Power near Port Qaism for fishing or picnic ?
I said yes I several times.
He asked again that have you ever seen any strange thing like Ghost, witch or monster ?
I started laughing at his question and said not didn't seen ever in my life and I don't ever think that they came visible for normal persons.
Than he show me a picture of that place and highlighted me a thing in that picture which appears very strange to me for the first time after watching that picture I start thinking is it real or fake.
below is the picture (Original as it appears to me)
UPDATE: one of web searcher proved this is fake
