Figmental crises

I got bored and imagined it would be fun
if I can shrink and be the size of an ant
and dive into my fish tank
to swim under water and navigate through the aqua plants
as a miniature man
While my original self could watch from outside
as I glided about aimlessly inside
But then I'd surely see myself getting ripped into shreds
by the fish tank fishes from all sides
and there ended this useless exercise

I don't understand this existence
