This isn’t really my own belief per se, but something I recall from my childhood that was believed to be useful. When I was little, I noticed my mum had taken an empty carbonated drink bottle (unlabelled), filled it with at least 3/4 water & laid it down sideways on the soil of the flowerbed in our garden. I asked why she did that & she told me it was supposed to scare cats away, so they wouldn’t pee/poop in our garden (or at least that part of the garden). Apparently they’d see their reflection in the water & get spooked away? I don’t know, it sounded pretty dumb to me, but I never actually saw a cat react to it, so I still don’t know if it worked or not, LOL. My mum certainly believed in it, though & I think one of my aunts tried the same trick, so it must’ve been a thing back then (this would’ve been in the 1990’s). Sounds kinda silly, doesn’t it? 🤣
I used to believe dogs were boys and cats were girls of the same species.
When I was little, I thought the singular form of geese was "gee"
I used to believe that a swan was a made-up animal for the ballet "Swan Lake". I didn't know a swan was a real animal until i was in 4th grade
I used to believe that clay pigeons were pigeon-shaped clay figures.
I used to believe that crows and ravens were the same species; crows were males and ravens were females. This belief is because Raven is a girls' name and Crow sounds more like a boys' name
When I was little I belief to unicorns existed.
I used to believe that a pigeon was a type of pig
I used to belive that if I would arrive near the sea the water would pull me and I would throw myself in the mouth of one shark and I would live there forever .
I used to think that a sea lion was a hybrid of a seal and a lion.
