I once had a fairly large plastic toybox, which was pink and white. My parents were puzzled by the fact that I would often pull out all of the toys and sit in the now empty toybox. To be honest, I don't know why I did it either.
I also liked to spend a lot of time in my basement. I still do, actually. Mostly, I just pace back and forth, talking to myself, but when I was younger, I had "adventures" down there. I would pretend that I was in the mountains, or in a cave, or underwater. Usually, I kept the light off, unless it was dark outside.
It actually never occurred to me to climb into cabinents...
