Did anyone have an "imaginary friend" made of their OCD?

When I was a kid I had an imaginary "friend" that was basically a manifestation of my intrusive thoughts. I didn't like him and wanted him to go away, but the more I told him to stop, the stronger he'd get.

Did anyone else have this? Is this normal for OCD as a kid?

Or if you just had an imaginary friend in general, feel free to share. I'd like to know what other ones were like.
