I think with people that are quite sensitive to motion sickness this is not that uncommon.
There is an I-MAX theater here that shows films that engulf the audience that causes many people to get sick. Lot's of people cannot take it and leave the show. The movie is so real that it gives the body a sense of motion when you're just sitting still. But the eyes do not know this, and gives the same effect as motion sickness.
