That if I acted like a cat long enough, I would turn into one, this lasted for seven years. And that there was a witch in a tree next to my house, and my cat could teleport, and the way animals got pregnant is by having another animal sniff their butt, Africa and Asia were countries, Germany was right next to Canada, and that the bluish-looking silhouette of trees/mountains in the distance was the ocean because it looked blue so it had to be water. and that my toys would come to life if I played with them enough, Russia and Ukraine were the same thing, Antarctica was full of cats, and South America, North America, and the United States of America were all one and the same, but Canada was its own separate thing.
I also believed in the tooth fairy, santa, ghosts, bigfoot, the easter bunny, and all those things were all real.
