Speaking of Stephen King....
Some of his subject matter might provide ideas - I've had dreams (when I've had stressful days, I guess) about images I formed in my mind after reading Tommyknockers:
Get some of those 5-gallon plastic water bottles, you could cut them and fill them with weird things (dare I say dolls?) then super glue them, attach some rubber tubing and have someone design a way to make them "glow" from time to time; make like a mad scientists lab.
Or how about Needful Things? Any of King's stories that have a good image of a physical reality of some sort that can be reproduced might give you ideas. If you like, I'll post more.
