Where to find dreams

Its a bit difficult because I created a survey but no one is answering it.
Here are some responses.

The trouble with dreams is that they are often very personal and context specific. So for example if a person was dreaming about a ghost they may have read a ghost story - it doesn't necessarily mean that person is dreaming that image because they are feeling a particular emotion. I think this will make the idea tough to follow. Also, in some there is a lot of content - how to minimise it into a coherent and simple image.

I thought about other ways of presenting dreams and maybe looking specifically at what the 'symbols' can mean (emphasis on the can!)
