I believe in everything until it's disproved. So I believe in fairies the myths dragons. It all exists even if it's in your mind. Who's to say that dreams and nightmares aren't as real as the here and now?
When you're 14 anything with a sword and a dragon is pretty cool. But when you're 21 and you've read 2 000 fantasy novels you start to realize that some of those books well they weren't really good. OK let's be honest. A lot of them were crap.
