Just my luck.....

I was in a Skype call with him at the time when it happened, Obliviator even sent a picture to prove it, it happened. Plus having heard her talk with others and briefly talking with her over group Skype calls before I can guarantee you she is mentally sane (or at least if she does have a mental disorder it's not intense enough to cause something like that). And this didn't just happen when she was sleeping, there were a couple of times where (or at least according to Obliviator at the time) she was totally conscious and cuts randomly started appearing. And, I'm sorry, but I highly doubt you could make multiple large cuts run down your body just because you thought about it really hard. And to my knowledge this whole event only took place over one night, so if that whole power of suggestion thing you brought up was really at work here, it probably would have continued happening.

Isn't it interesting that nobody ever says "I've actually had some violent paranormal shit happen to me", but instead you can never hear the end to "Shit's true -- happened to my friend once." I've never met one person that claimed to personally experience something, though even if they did there's no evidence it transpired.
Interesting side note; Are you aware that some humans will spend years of their lives going through college getting a degree, just so they can then boast that the freaky-dumbshit they believe is true? Did you know children will not do anything even remotely close to this because they know it's a useless waste of time? Also, people will then bring up some random person or event that they believe completely falsifies what another says.
