What could be the reason for me passing out in Biology?

So today in Biology, we were dissecting a squid. I didn’t find it gross or repulsive and there was no blood. (I faint at the sight of blood)
All of the sudden, I started shaking, everything went white and I passed out. I wasn’t hot, so it couldn’t have been a heat stroke. Could I have passed out because of the smell of the squid and latex gloves? Is that even possible? If not, what are some other possibilities?
