I've been shooting my short for abour a week. I've just been shooting small things, and cut aways. The main scene of the film is going to be shot next week, and im not sure how to light it.

There's a girl siting on a bed reading a book and something is crawling from the floor up her bed. You see the through the eyes of the thign thats crawling. (this is a horror/comdey) How do i light this scene?

Also where can i get some cheap lights do to this?

thank you
