I had some for a brief period. More like characters I imagined interacting with me, and with one another. I could have told you they weren't real, of course. My possibly-incorrect recollection is that I thought them up on a long road trip, and that they rarely "existed" anywhere other than the car. A couple hours-long trips to relatives' houses every year, usually one big vacation involving entire days in the car, maybe one or two other longish drives a year, plus shorter journeys pretty much daily. Wonder if tons of constrained, boring car travel has anything to do with it—if not causing the phenomenon, then encouraging it, anyway.
