Hey guys

i am in the middle of shooting a low budget horror movie which is about exorcism. In one of the scenes, the possessed crawls up the wall and to the ceiling. now i don't want to use CG to make this. At the same time when doing it practically, imagine she is crawling on the floor which is set up like the ceiling, how do i get her hair, chain, dress to hang in the other the direction(like if you are actually walking on the ceiling).

i don't want to make her cut her hair or make her wear body hugging clothes to avoid the above.

even if you have a completely different approach to shooting this, they are welcome as well.

thanks
