I was once living in a basically haunted area. There in a very small room ( not big enough to have a double bed ) with all windows and door closed I started killing mosquitoes, and at the beginning there only only a handful of them but every time I killed one it seemed ten more appear out of no where!!! In a completely enclosed area. Within few minutes the who whole room was buzzing with mosquitoes, making it almost completely dark. Freaked the hell out of me and I had to leave the room at the middle of the night !!! Stuff like this happens.
