So let's say you've had a dream, but only remember bits and pieces. If you become lucid can you set up those events and just have whatever the dream world wants to do to connect the events. I ask because I had a very interesting dream last night involving about 300 mattresses and huge bouncy castle like things.

I only remember small pieces, but I feel like it would be interesting to enter the dream a few times and see how it differs each time I have it.
