DAE feel physically sick from Minecraft?

When I play or watch someone play Minecraft for longer than a few minutes, I feel incredibly nauseous. Minecraft music has this effect, too. I can't even think about playing Minecraft without feeling vaguely ill.

Edit: Very glad I'm not the only one feeling this. To the people who suggested changing FOV, bobbing, light filter, etc, thank you but none of them worked for me. Also thanks everyone for explaining it's motion sickness. Makes so much sense. Maybe I'll try Dramamine before playing some time (although I might fall asleep instead of being having nausea)
