Also look up Dream Incubation.

You want to day dream and visualize your starter scenario. Put detail into it, what type of mobs lurk there (elfs, trolls, wraiths, etc...) Also, how does this place look like, what type of noises do you hear, what does it smell like, how does it feel like, etc... Make it a vivid daydream and especially do this while you are trying to fall asleep in bed. That should immensely help.
