A stopped escalator is just a staircase

And yet your foot leaves without you

Why do you stumble on a stopped escalator?

Your brain has memorized the push of the escalator

It files the move in a drawer, ready to pull out

Even warned, it happens

Two memories share the same body, and the one from the move decides faster than reason

It has a name: the broken escalator phenomenon

Like a phantom step or the sway after a boat ride, the body corrects a motion that already ended

Your brain was sure it was right
