A childhood belief about imaginary friends

I remember a few imaginary friends growing up:

From about 6-7 I believed my name was Kelly and I had a host of older brothers (actually I was the oldest with a younger brother and sister). Some of them I remember were named Kevin and Ken. I can't remember how many of them there were but I do remember we worked in the circus as an acrobat act.

Later in middle school (about age 12-13) I had several animal friends, mostly a big Golden Retriever named Brownie and two squirrels named Chip and Dale. There may have been others; I remember a cat and a bird but I don't remember their names.

In high school I pretended (to myself) that I had a daughter named Faith at age 16 on my birthday. I imagined caring for her and reading about her stages. Even now at 29 I think about Faith and how now she would be 13!
