JesusLives, I used to have imaginary friends, kind of.
As a toddler I had no friends. So I would go to sit under a large tree in our garden and talk to it about my troubles and worries. Nowadays I think it was more like me praying than having a tree as a friend. After we moved I continued praying, but this time I keenly believed it was a Guardian Angel, Miriam, that I talked to. I can still remember how she was there when I was scared of the dark.
I even today wonder how I became friends with a tree.
