I used to have a fear of taking a shower when I was around 7-8, and when I took one I did it as quickly as possible.
Why?
I believe King Tut's mummified body would fall out of the ceiling and into the bathtub.
However, what I never questioned is what was King Tut doing on my ceiling...
A childhood belief about bathrooms
