Aww. I'm sorry billi!! Maybe you trigged (as said above)? Maybe you saw a parachute or something with prisoners (or something with rough looking men?) If you are in someway nauseous when flying, maybe that contributed to everything?

Oooh! Maybe you were stuffy in the room (or wherever) you were sleeping, which lead to the no-ventilation? And regarding the scent, maybe it could have been something that you didn't like the smell of? (When you said "sickeningly sweet," I thought of a candle. Perhaps it's that?)

Well, just take it easy billi!
