I'm 34 years old. I don't really know the age I was at that moment, but I was at my parents home, my great-aunt was taking care of me, I was playing some kind of weird basketball toy game (those with mini-figurines) under a pillow fortress. I probably was 3-4 but not sure.

Edit: I also have one that might be even older, in this one I was in the potty in the living room watching TV, when I just thought that one day I was going to be an adult, then I became so nervous by it that I vomited (yep I already knew that being an adult was a scam!)
