[Portal] If a celling were to come down to crush me, and I place one portal directly above me, and portal directly below, and the celling meets the floor, where would I go?

There's no space "inside" the portal. Entering one portal *is* exiting the other portal. There is no significant void space between them.

So if this scenario was somehow created you would be crushed against your own body.
