It sounds a bit like WILD, going straight from a waking state into a dream. A lot of people experience shaking or images or sounds during WILD initiation, so it's not unusual. I'd recommend taking a look at some of the tutorials for some more ideas and see if you're interested in going in that direction.

If this is something that comes relatively easily to you, you could also take a look at the Dream Re-Entry tutorial (also known as DEILD). Basically, you take the last dream you had and focus on it until you are sleeping again and re-enter the dream world.
