Scratches on my arm and face?

My brother was sitting in his room, and all the sudden he feels a burning sensation on his right cheek and left arm, and they start to bleed. After he cleaned them up there was 3 scratches on his lower arm.another 3 a little above but smaller, and 3 on his cheek. We have no idea what could have caused this, we even went as far as to say it could be "Paranormal" since my friend was messing around with a Ouija Board on his iPhone, we even felt strange stuff around the house since last week. But those are just thoughts. Is it Medical or what?

Why can't my iPhone send or receive pictures in text messaging?

My dad bought me the iPhone 4S unlocked. I got the prepaid service at tmobile which was 50$ unlimited talk text and web. I can't send pictures during text messages and I can't receive them. If someone sends me a picture I don't get it, it's just blank. The little camera icon next to the text area to type is light grey indicating I can't press on it. I can only send or receive during iMessage. Please tell me why this is happening.
