I won't be surprised if 'imaginary friend' thing is probably tied to specific culture/regions. I grew up in a SE Asian country and there, we never heard of kids talking to imaginary friends. I myself grew up only imagining that I was fighting with robots, cars, machines, etc. When my sister played, she pretends she's selling some stuff like food to us (my brother and I). I also used to imagine that I am superman or someone who can fly. That's about it. Never imagined having an imaginary friend who I talk to regularly, and never heard of my friends or any family members saying it's normal to imagine like that.
As I am now in my 30s, I think of ways to design different room and land layouts for my imaginary apartments, houses, island, etc. That really helps me fall asleep quick (as a side benefit).
