If you don't mind me asking; what were your thoughts on it after reading up?
Solipsism? I get the same feeling that I do when I think of religion, really. And that just makes more questions than answers. And for some reason, my mind starts saying "Well, what if the only thing that's not real is your own mind?" <__< That's my argumentative personality slipping through though.
I'm sure there's a term for it, but it's slipping my mind so late at night.
Edit: Now that I think about it, solipsism is kind of lonely to me.
