Based on the first couple of pages I thought this thread would just be full of stupid crap, but since some have an interest here's one that doesn't fit the "I heard a noise, captured an orb on camera, etc.".
A couple years ago we moved into a house that seemed fine, the only weird thing I noticed at first was that the little girl that had lived their before had drawn/written some weird shit on the walls in a couple of the rooms. I wish I had taken pics cause I can't remember all the details but they got painted over.But to summarize it looked like some weird animal. One of first things that happened to me was when I was just laying on my bed watching a Ween concert on DVD. I'm just laying there and all of a sudden I feel a sharp stabbing type of pain on my left side/my stomach for a few seconds, maybe 3-4 then it went away and I was thinking wtf?
So I lift my shirt up thinking maybe I got bit by a bug, but to my surprise there was 4-6 scratch marks about 4-5" long lined up next to each other kinda like fingers or claws. I can't remember the exact amount. They were fresh and it shocked the hell outta me.
