I had that once. Extreme headrush. It's funny how it was also froma waterfall bong...I remember thinking of a level in Super Ghouls N Ghosts and flying fish going in a infinit manner kind of like an 8 form. And I remember hearing laughter and I was home alone and umm also the color purple. The loops of the way the fish were going was purple and the fish looked like those underwater fish from Super Mario World.

I was scared as hell because it was so new to me, but damn, looking back on that makes me wish it lasted longer.
