I've experienced ghost. I know for a fact there real cause my dog was barking in the hallway at nothing and I saw a white flash of light. You can call me crazy but when you die you become a ghost or spirit. It's how this world works and its in so many mysterious ways. I know because I've heard my voice being called and one time I was just getting up and it said Hello to me. Some of the people I've talked to have also experienced paranormal activity. Believe me it's real and you can say it's not but it wont make me believe you considering I have experienced it.
