There are two sound effects, one is the environment fog sound and the other one is footstep sound which is from the woman. When the fog is gone, there are more exits that can be seen. The hand is moving with a camera view(user view). It should have to be an arm instead of a hand. Because we can see our arm from a hand.
I made one of door is different with yellow and white lights. In my nightmare, there was no exit and I could not find an exit. But in this VR, I added the one exit.
