I believe in ghosts. In fact, I've seen one. I was spending the night at my mom's friend's house. It was late, around 10 I think, and my brother and sister and my mom's friend's kids and I were playing outside. We were playing some sort of tag game. At one moment only my sister, my mom's friend's daughter, and I were outside. My brother had just went inside. We were just hanging around by the back door, and all of a sudden we see a man and a dog back towards the woods. Here, let me show you a crude Paint drawing of the scene:
The man was wearing a construction worker's clothes and he had a hardhat and a flashlight. The dog was walking in front of him, not on a leash. They were walking in the direction of the garage with the flashlight pointed that way. At first didn't say anything. Then the girl (not my sister) yelled, "Who are you? Get out of our yard!" or something like that. He didn't answer. Instead he and the dog kept walking, and they went behind the garage, out of our sight. We quickly ran up to the garage and looked where the man had went--he was gone. They were both gone. There was no light from the flashlight. There was no movement anywhere. They just vanished. The only explanation is that they were ghosts. Why were they there? What were they doing? I don't know, but it was freaky. Even freakier is that it happened on Friday the 13th. I don't believe the date had anything to do with it, but it made it a little more creepy.
