I do! My imaginary friends are usually based off of the "obsessions" I get with certain shows, webcomics, etc.

Mine is taken to the level of some hallucinating though, primarily tactile. I feel my imaginary friends when they obviously aren't there, but I can feel them touching me, tapping me, etc, sometimes with malicious intent. I am going to a psychiatrist about that soon.

If you start getting anything like that, or hearing them or seeing them, make sure to tell your therapist! You don't want it to get worse!

But I think that the imaginary friends you have is relatively normal, I wouldn't worry yourself too much. :33
