I Used To Believe My Butt Was A Second Face!
This one is slightly bizarre, but I used to think
That when you had a haircut and it had to be right below your ears, you had to bring a picture of yourself as a baby, so that they would know what length they had to cut it to, to match the shape of your face. I honestly don't know why.
When I would hear my pulse in my ear, I thought there was a little person playing a drum. I thought this was what an eardrum was.
I used to think when someone had wrinkles on their forehead, it meant they had a headache
I used to think that bleaching your hair meant washing your hair with toilet bleach.
I used to believe that my body was a costume with me in it.
I used to think that blind people always had their eyes closed.
When I was little I thought that dying your hair means you kill your hair.
I used to be terrified of blind people because I thought that they had empty eye sockets and that’s why they wore sunglasses. However, I was never freaked out of Geordi LaForge from Star Trek TNG
when I was young I used to believe if I squinted my eyes and it was windy my eyes would stay like this forever
