For your "creepy things kids say" I dot. Remember this but supposedly when I was young we lived in this creepy ass house and had an imaginary friend name Jonathan. My mom said that I described him as a teenager who had now lower jaw and was covered in "some weird red stuff" a while later I was about 11 and I was talking to my mom about this. We still lived in the house and while we were talking my little sister who was now I want to saw three came in. She heard us and asked why we were taking about the boy upstairs. I guess she saw him too. Slowly I start to get weird memories of him. I remember he would tell me to do weird things like go in the basement and look in the walls. There was definitely more weird stuff with him. We aren't in that house anymore and I still wonder what was in those walls...
