When i was around 4 we had a big pool in our back garden , i didn't know how to swim , meaning that my parents never even let me go near the deep end ( even if i did have those blow up arm things) ... after one close incident , my parents got me into believing that the reason why they didn't want me in the deep end was because a mean monster called Madame Hozze ( hozze meaning small pool in farsi) lived in the deep end ...and that she swallowed all children and that after they never saw their moms and dads again .. .i was traumatized ..and therefore didn't swim for years !
