When I was about eight or nine, my grandfather took me to a marina. The sea was so flat that I didn't think it could possibly be water and wanted to walk on it to check. When Grandpa said no, I thought that you had to be older to legally check if something was water or not.
I used to believe that the boats in the ocean could fall if the continued surfing because of the shape of the Earth was round...
When I was a child I was used to putting my tete under the water because I believed that I could breathe under the water.
I used to believe that the red sea was red
As a child I used to think that the sea was infinite.
I used to think that when it rained, god was crying.
I'm not religious but i believed it.
I used to believe that when it rained in my town, it rained everywhere.
When I was a child I used to speak to the sea and I believed it could answer with its waves. So, when it was rough I tried every time to calm it down with compliments and affectionate sentences.
I thought if you stayed in the water (pool, shower, bath etc) too long your hair would turn red like Ariel's from The Little Mermaid.
Our nanny at the kindergarden told me the group's pet, a goldfish will become a shark as we feed it too many times.
I used to believe when it rain that Jesus is crying
When I was younger, I always thought that the name of the ocean was floating in the water, like you see on maps. You know, ATLANTIC OCEAN, in huge letters, anchored to the sea floor, that you can see when you are flying across the oceans. I was a junior in high school when i was set straight.
I used to think "spitting", as in, light rain, was when aliens and or angels spat down on us for the hell of it.
One time when my brother and I went to the beach, he was 7 and I was 5, he swam out really far in the ocean while I was wading in the shallow part. 20 minutes later he came back telling me about the pirates and mermaids he saw and I fully believed him [3
I thought that the sound you hear when you put a seashell to your ear was a "recording" of the sea waves and that after the shell was out of the ocean for the same amount of time that it was originally in the ocean the "recording" would end and the sound would stop.
I thought a tidal wave was acutualy a title wave because if the wave was big enough it had its own title!
The region I live in has a river and a beer named after it. This river is very fast flowing and dangerous and as a kid I was always told I was never to swim in it or drink the water (for my own safety.) I always thought it was because the brown river water was actually the beer of the same name and they use to bottle the river 'beer' and if I swam or drank it I'd get drunk and contaminate the beer.
When I was little, I had a debilitating fear of sharks, so whenever I would go to the beach, I would sit on the shore and refuse to go in the water with the other kids. To fix this, my parents told me that every beach has a net around it to keep the sharks out, but fish and dolphins could get through. I believed this about all beaches until I was about 18 years old. How they explained it made a lot of sense...
When we would go to the beach we used to play in the waves. my brother told me they were whales. and i got so freaked out every time a wave came, i jumped as high as i could, not wanting to hurt the whales. boy , it was hard to keep up sometimes.
I used to believe that gas bubbles in swamps came from turtles breathing underwater. I didn't find out until high school that my mom had made it up.
