My Aunt used to tell me that if I went to sleep with my hair wet (from taking a bath/shower), I would become blind.
A childhood belief about hair

others believed things like this
- i used to believe that if someone take his bath with a hair shampoo, their body will become hairy.— roslin
- I used to believe that take a shower meant to go steal a shower from the storeAnon
- I used to think that when I was in the bath I shark lived under the bath and that ig might come up and bite me— ------------
- I used to think that toilets led to the shower head. That's why I never took a shower :D— scared
- I used to think that if you take the plug out of the bath it will suck you into the bath— awesome kid
- I used to think that when people were taking their contacts out that they were taking their eyeball out :) — Jen
