I used to believe that when I started menstruating, I would bleed to death from losing too much blood.

I used to believe that bruises were rotten blood.

I used to believe that nothing existed behind me when I wasn't looking. Things only existed when I can see them. I think I still believe that.

When I was an early elementary schoolboy, I used to believe that if I went to sit on a chair, and it was warm, a girl had been sitting there.

When I was little, my grandfather (who had a big pot belly) would always burp when I poked him in the belly. I could do this ten times in a row and he would burp just as loud each time. I assumed that a person's belly acted as a "burp button" and that people burped automatically when their bellies are poked. I tried it on myself and nothing happened. After repeated attempts and no burps, I began to believe that my body was defective. My parents reassured me that I was healthy and explained (to my disappointment) that my grandfather was only playing along. I don't know why I didn't think to test this out on anybody else before assuming that there was something wrong with me!

When I was young I loved to watch science and nature shows all the time... even if I didnt always understand what was going on. I guess one time I saw something on how white blood cells and platelets worked. I got it sorta twisted in my head, and I thought that they were little robots that lived in your blood. When you got cut, they would go to work and repair you with little bits of yourself. So... logically, one should eat scabs, lick the blood off your wounds and eat your boogers so that you could recycle those materials when you hurt yourself or were fighting a cold.

when I was 5 whenever I blew my nose my mom would say "blow it out to sea!" so I always thought that there was an island in my nose, and the snot was water. So if I didn't blow my nose often enough that the island would flood and all the people would die!! Yeah, I was one weird kid.

When I was younger, about 5-8 years old, I believed anything that I thought, day dreamed, or make something in my head, that it would show up in a thought bubble for everyone to see what I was thinking.

When I was little I believed there were creatures/people of some sort (kinda like the builders from Fraggle Rock) that lived inside of me and made my body functional. Every time I would eat I would picture my chewed up food going down a shoot and landing on a conveyer belt where it would be divided. Same with them being in my eyes and all over the rest of me. So when I was sick I thought maybe they were dying.

I used to believe in the 'little men' that worked inside your body.

I used to believe that when you smelt of something, breathing out onto it would ruin the smell. To this day I do not exhale on flowers, but point my breath in another direction before I sniff them again.

when I was about 4 or 5 and at my grandfathers house, i noticed that my mid-torso moved when i breathed. i thought that only adults were supposed to do that so i held a pillow against myself and took slow short breaths so the pillow wouldn't move (i was afriad someone would say something to me about it if it did). Even now i try not to move too much when i breathe.

I used to think that when people said they had 'butterflies' in their stomach, there were real butterflies flying around inside.

I thought that if I said "Excuse me" enough times, I would be even for all the times I burped as a baby and never said it. I must have said it at least 500,000 times until my teens or twenties just for good measure.
