writers block

This evening I got an itch to be writing. My mind won't stand still long enough to form a premise but it wants to write. I spend all my free time reading what others have transcribe from their thoughts and I want to do the same.

I don't necessarily want to be published (although that would be pretty cool!) but I want to be actively writing, putting my degree to use ... even if it is just for me and my eyes (which it will be)..

I don't know what it's going to be about but I know that it won't be realistic. I live in a fantasy world where vampires are beautiful and wizards speak with English accents. What fun is it to write about something that could actually happen?
