I used to fear the deep end of the pool when it was dark. Even though I would be swimming while it was light and knew there was nothing there. I would never go near it while it was dark and always kept an eye on it while in the shallow end.
The Jaws movies was partly to blame as well as when I was young I used to swim in a creek hole that was about four or five feet deep and could feel the frogs swimming by my feet. I think crab nipping at my toes also added to this fear.
