@Coffin/ I think what the Librarian was trying to say was if there is no evidence/proof and you believe in it then it will become a reality(to you),for example. There are two people. One person believes in god the other doesn't. To the person who does believe in god, God is reality,to them. To the other person, god does not exist and has never existed. I think this is what he/she was trying to say but about dragons, and then he/she started to drift off to the topic of reality. But seriously both of you, you guys are off topic.
