Not the most dramatic, but when I was really little I remember play fighting with my brothers, and falling backwards off the bed and hitting my head against a dresser.
There was no wound or anything but I remember seeing all kinds of fucked up colors at the moment of impact. Despite being a huge crybaby, I’m pretty sure I didn’t cry or freak out, I was just extremely fatigued.
I wonder if we should have gone to the doctor. I don’t think you’re supposed to see TV static and rainbow vomit when you bump your head.
