What can you tell me from my childhood imaginary friend?

I used to have an imaginary friend when i was a toddler, and i called him donclee (i dont know how to spell it or it it was two words or one) but anyways i had a description of him and everything. I said he wore overalls, red boots, and blonde hair. I called him my little brother for some reason. I also came up with weird stories of him dieing and stuff. Was donclee or maybe don clee? ever a real person or was this just from my imagination
