In this category, general means just that. These are the sorts of things I'm thinking of:
The latest book you've read / your favourite book
The most recent film you've watched / your favourite film
Any paranormal occurences you've experienced
What would you do if you found out the world was ending a week on Wednesday?
Who would you want to be holed up with in a post-apocalyptic world?
Any topic you think that people may be interested in (horror and dark fiction, probably)
Images of you recreating classic horror scenes (!)
News items that have caught your eye
Start a topic and away you go!
