I pick Ghost Stories. Not that I have a lot to say about those, but anyway.
I love ghost stories. And they scare the shit out of me :-p
It's a completely irrational fear, I'm 24 years old and a university trained scientist, you know, I shouldn't be afraid of the dark :-p
But oh yes I am.
I LOVE reading ghoststories online. And I know I'll get scared and wonder why I read them. But I still go on. Preferably when I'm home alone :-p
You see I just love stuff that can provoke a lot of emotion, such as genuine fear :-D
Ummmm next up ...
2. The 'end of the world'
