In my dream i created a new type of thread where people make up situations and people give advice in order to find out 'what happens next' like some kind of interactive story.
Eg. Someone posts 'i fancy the head teacher shall I ask him out? ' and people know it's a made up scenario but they give advice and the OP makes up the story about what happens next and it keeps going as if it's a real post. It sounds boring when I write it down 
but last night it seemed like a cool idea
