Most of these only get triggered in me under specific circumstances.
I really only get claustrophobic when I don't have an easy way out of a confined space, not in all small spaces. Once I entered a 1 person public bathroom. The lock was busted, came undone, someone else came in, and locked behind them. They must have been hard of hearing because I called out like 3 times. I felt trapped like I never had before. I was like 10 feet away, tops, and I heard everything. o_o
So um... yeah, that gave me a minor fear of single-occupancy public bathrooms.
