Is it normal that I don't like going in bathrooms behind people?

Sometimes floaters can be spooky.
I ask to use someone's bathroom and everything appears to be in order. The top toilet seat is down and maybe even has one of those carpet seat covers. There are aromatherapy candles, sea shells, and little decorative soaps. Unsuspecting, I lift the seat and THERE IT IS! Deliberately afloat in a bowl devoid of toilet paper it's brown comrades long since flushed the lonesome fibrous remnant; the FLOATER.
