Back then, this used to happen to me a lot. Whenever I would go to use the bathroom that's somewhere public, like let's say the movies.. When I'm in the stall I'm terrified of flushing the toilet because I always feel so trapped in the space that the stall offers and I can always feel the violent flush of the toilet throwing itself towards me. I would usually kick the switch to flush the toilet while covering my ears and backing towards the door so I could be away from it as possible without uncovering my ears. Now that I'm somewhat over it, when I look back I wonder if it was normal or not? Possible some sort of phobia or something along those lines?

I cover my ears when flushing one of those violent commercial strength crappers and I move back because it seems like you could be soaked.
