Thinking about it, its pretty hard for them to give anything other than a journal or a general creative writing task. They would never specify poetry for one, and if you think about it, trying to interview someone about a story would be dumb and it would just end up a normal story but with occasional interjections and a intro and conclusion. They are generally based on very minimal prompting and stimuli.
I have a couple ideas and a few passages which I commonly use to describe emotions and a couple plot lines.
1) Drowning - I have almost drowned a few times, its a very interesting experience and an awesome imaginative journey. You go through a number of stages - pretty much all of the typical dealing with death stages - and they are actually catalysed by thought patterns in your mind. Its pretty much the definition of an imaginative journey.
This is my main original idea. My other ones are inspired by movies and the like.
2) Murder - Death Note style. The killing is a very small part of the story, in fact, its only a couple lines, but then the protagonist has to deal with, once again all the different stages of death and the internal desire to kill again. If I have time it goes into a more intellectual battle.
3) Journal - plot driven time travel-y thing - basically goes back in time by for each entry and tries to make sense of events that were originally really simple - in forwards mode - but it brings light to the things you take for granted in life.
Which one sounds the best, any feedback or suggestions are good.
