A childhood belief about imaginary friends

As a three or four year old only child with no friends nearby to talk to, I often spent my time telling my parents about Mr. Ghost. All I can remember about him is that he lived in the snow (I think this was to get them to take me to the snow), and that he ate people. I think I remember telling my dad that he used the snow to whipe the blood off his face. And somehow, I'd become friends with him when he took a vacation from the snow.

A few years later, I decided that I had an imaginary unicorn named Melina. She was the unicorn goddess, and she kept me entertained. I think I managed to convince one or two people that marshmellows were made of unicorns, so they should stop eating them. I'm a fairly normal teenager, it turns out.
