This particular manifestation is interesting, although not surprising - it's just adaptation. I was in a psychology department in the mid 90s when people were experimenting with really basic VR, just a headset and a glove. When you pointed with the glove you moved that way in the virtual world. Even after a short time with the headset on, when people took the headset off, instead of walking out of the room their first move was often to point towards the door. The human brain is really prone to immersion.
