dream friends

Similar to imaginary friends, when you have a dream and people in it are your friends but they don't look like anyone you know and don't exist in real life. They just represent the concept of friends in the dream.

"I had this dream last night where me and my friends fought a battle but they weren't my real friends, they were my dream friends."

"I dreamt that me and you were sailing in the olympics, well it wasn't you, but it was a dream friend that was supposed to be you."
