I was pulling a large cardboard box off a van. It was made of very thick cardboard designed to be carried. The box had holes in each end to use as handles.
So I had my hand in the nearest hole, palm facing up, and was pulling with all my strength. Unfortunately I think the floor of the van was a bit wet or something and the box was hermetically sealed to the floor.
I was trying to overcome the hermetic seal by pulling with all my strength. Just then the cardboard ripped and I punched myself in the face.
I hit myself so hard that I actually staggered around for a few seconds with stars and tweety birds around my head. Seriously. I always thought the stars thing was a cartoon device but I actually saw them.
I’m torn between feeling stupid and being quite impressed at how hard I could punch if needed. Certainly left me reeling.
Another time I found an abandoned TV on some waste land and I wondered what would happen if I threw a rock into the screen…
The subsequent explosion kinda happened in slow motion. I saw a slowly expanding sphere of broken glass heading towards me. I managed to turn away and protect my face. Got away ok but then I was a kid then and kids always do.
