I used to believe that all roads were perfectly straight. From my too-short-to-see-above-the-dash perspective, I noticed that my mother had to keep turning the wheel (for curves in the road and such) and I remember thinking that something must be wrong with our car.

I used to believe that at night when I was asleep all my furniture including my bed was replaced with identical copies by the fairies. I started putting a cross in pen on my bed to fool them. They obviously sussed it though because they always copied that too.

This is my experience with my daughter's imaginary friends. She had three main imaginary friends : Meanie...mutagenic bat/rat/boy with an attitude problem, Gogonagi...a giant six foot long rat....and Silly Beaver...a tree eating rodent. What upset me most was my daughter would wack herself on the head over and over saying.." Get out of there ! Get out of there !" ...when i asked what was going on she would say " That silly Beaver jumped into my brain again!!"....
I never really got any kind of explaination from her as to how this all happened or came from or meant.
I would sort of bite my lip and hope that it didnt mean she was truly crazy or possessed or anything...so far she seems to be ok for a teenager.

vitus the mad (from make-believe : imaginary friends)

I used to believe that the fluorescent light in the kitchen couldn't just be turned on with a switch. You also had to blow on it. You had to blow pretty hard (by then of course the light would finally come on). I was about 3 and had to jump pretty high to make it work.

I used to want to be a con artist,I thought you could actually go to college to be one,and whenever someone asked what I wanted to be when I grew up,I replied "A con artist."

R.P. (from the law : criminals)

I used to think certain numbers had personalities.9 was very smart and manipulative, and if other numbers didn't watch it, she'd add herself to them and rob them of their rightful place in the "teens". 4 wouldn't become 14, but only 13, etc. Four and six were nice, but easily fooled (especially 4), 7 was smart and 8 was bossy like my sister. Go figure! ;)

LHW (from language : counting)

I've always loved drawing, mostly people or faces. But when I was little, I believed every single doodle you did was somehow transported to a different dimension to live forever – and I do mean live, as in walk, talk, think and feel – in the World of Drawings. So whenever I drew something ugly I’d be consumed with guilt. I thought I was responsible for condemning this defective drawing to an eternal life of mockery and misery. Boy, did I use rubbers back then.

Bel Seslaf, Brazil (from kids : hobbies)

When I was a little kid I thought that if you gave somebody your cold you would no longer be sick. So when I had a cold I would kiss people and then give them two short breaths in their faces to give them my cold. Nice kid. 

Rocketeer  (from body functions : being ill)

The trails that aeroplanes leave across the sky are obviously created by pilots leaning out of the windows holding a piece of chalk, so they know where they've been. That's what I was told anyway.

Andrew (from transport : aeroplanes)

I used to believe that cough medicine had a toggle effect. In other words, if you took cough medicine when you didn't have a cold, it gave you a cold

Little Ronny (from body functions : being ill)

My dad and the guy next door had both lost a finger in separate accidents before I was born. I remember thinking that all men, when they reached a certain age, had one of their fingers fall off.

Anon (from body parts : general)

When I was about 4 I would worry about robbers breaking into our house, but only till midnight. Because after midnight the witches would come out and no robber would be out when the witches were out.

Carolyn G. (from the law : criminals)

I used to believe that the dinasaurs aren't really extinct, that we are all really dinosaurs, but we're just asleep and having this incredibly realistic dream that we're people.

ERDOC (from make-believe : monsters)

When I was very young, I saw a picture of children waving at a fire truck. I thought that was strange because I believed firemen were evil doers who burned people's houses down.

Rob (from grown-ups : work)

I used to believe that airplane pilots drove really fast down the runways just to show off and have fun before taking off.

Anon (from transport : aeroplanes)

After learning that every person has a soul, I wondered where in the
body it could be located. Every body part seemed occupied. I finally
concluded that the chin was the only part without a function, so the
soul had to be housed there!

Darlene (from body parts : general)

The supermarket my mother frequented placed the Wise potato chips on the bottom shelf.
As a preschooler I used to run down the chip aisle in fear because I believed that the eye on every single bag of Wise potato chips was staring at me.
I believed that they wanted to "get me."

Anon (from neighbourhood : going shopping)

When I was a child, for quite some time I believed that there had been an enourmous disaster in the world in which everyone had been killed, I thought that I was the last human boy left and that all the other people were robots that had been created so that I would grow up in a natural environment to perpetuate the human race. (I was certain that there was one last real girl left somewhere as well) I used to sit my mother down, look her straight in the eyes and tell her, 'I know what you are, you can stop pretending. I worked it out.' Needless to say she told me it was all rubbish. Or was she just pretending... ;)

Noel Daniel (from kids : i'm different)

My sister would always bring a lunch size bag of potato chips whenever we went to a department store. She didn't eat them herself, she would feed them to the mannequins. She believed that they came to life after the store was closed and they were relying on children to leave some food behind because adults did not know they were alive.

Little Lisa's Sister (from neighbourhood : going shopping)

I used to believe that under the whirlpool that the drain would create in the bath, there was an eerie world of pigmy people who dressed in suits and played accordian music. The place was adorned with crystal chandeliers, red shag carpeting and flowing red drapes everywhere.... Very odd.
