Did she use your head?
No...
It would have explained much.
My mum used to wash us kids in the kitchen sink ... sitting us on the draining board and scrubbing away with the Life Boy soap. On one occasion I was, so she told me many years later, playing up and throwing my arms about. I knocked a frying pan off the shelf and caught it with my head. Apparently she had a great deal of trouble convincing the doctor of the veracity of her tale as he stitched me up.
I offer this as a possible explanation of ....erm ..... many things.
