Those Who Govern Sleep
I had alot of fun making this, the imagery in the spirits was based on some dream meanings I read about. There are equal amounts of death and life references shown. Sleep is a rather death like state, but it rejuvenates us and gives us energy. These spirits control her sleep and dreams. It may be more spiritual than scientific, but there are some parellels here with imagery in the movie too.
Thats about all the meaning involved, I mainly wanted to come up with something that looked really cool. Enjoy! Be honest.
