Meaning of “Alles steht Kopf”

Question

This is the German title of the Pixar movie Inside Out.

Given that the movie is about the world seen by the emotions inside the main character, I would translate it like “Everything standing in the head”.

On the other hand, it seems that auf dem Kopf stehen means "standing on the head" (like when you are upside down) — source.

So I am asking: What could be the literal translation of this German title?

Answer 1

Literally, it does mean everything stands on the head. Figuratively, it means either

everything goes wild (with enthusiasm, for example)

Or

everything is upside down, in turmoil, (even: all hell broke loose)

The latter would make most sense in this context.
