Yes, I feel like that also when sick - although I'm not usually sick to my stomach.
Illness in general does kind of slow down or put on hold our skill sets for dealing with the usual things - we do lose touch with reality a little but as long as its just losing touch a little and not losing touch a lot - then the feeling will pass after some rest, plenty of fluids and decent food.
Take some soup if you have not eaten.
A breath of fresh air also - 15 min walk around the block or something.
Reality is still here - so don't worry about that.
