A childhood belief about fear of

I was always afraid of toilets, like every other kid was. I thought that the louder the flush, the more likely I'd get sucked down into the toilet. Automatic toilets are the worst. I'd take some paper and cover the sensor with my hand so it'd think I was still there when I got up. Airplane toilets were soooo loud and had that horrible flushing that I'd cover my ears every time.

Odd thing is, no one really instilled that fear into me. I'm sixteen and I still covered my ears three days ago when I had to use the toilet in the airplane. I absolutely refuse to go to the bathroom if the toilets are automatic. And if there's a bar next to me for the handicapped people, i grab onto it with one hand so tight that my hand turns white.
