When I was 5 I learned Pig Latin! A fun little make believe language. Then I proceeded to ONLY speak Pig Latin. Even at preschool. For about 6 months. No one else spoke it so I thought it was hilarious. It went really great with the cowboy boots and bunny ears I refused to take off. No wonder I had no friends! Lol!
The weirdest thing i have done is while SLEEPING. That time i got into sleep SO good that i started dreaming seconds after laying on my bed. I had a dream that i was on some rice bag thing, And then i fell down. And guess what? i woke up and saw me tilted like 90 degrees when i was like straight o_o.
