Starting when I was six, I believed that if I didn't get to the sinks by the time the toilet was done flushing something really bad would happen to me(I dont' know what, just something). I also believed that if I left a book or magazine in front of the toilet a trapdoor would open and that my book or magazine would drop through. I don't know where this came from, but I believed it until I was 10.
