This is very interesting to read. I personally had an experience that increased my anxiety by using the video app Whirligig. It has a cinema mode that puts you in a room, but off to the left there's just a dark, open space. After reading House of Leaves I found myself really creeped out by the dark, open void that existed to my left, and found that feeling followed me for several hours after leaving virtual reality. It seems like in VR it's very important to have control of your surroundings, because a game/app developer could easily cause trauma or scare people who aren't expecting it. The immersion and its effect on your subconscious is really shocking to people who haven't tried it.
