Like a deep void of nothing. You’re not falling, because that would at least by something. Like being in the middle of blackness in space. It’s impossible to get your bearings. There’s nothing to orient yourself. You’re completely alone. Everything you used to know about life on earth is gone. No part of your body or mind has learned to speak the language of this alien dimension. You begin to sob uncontrollably because what else is there to do. Nobody is around to judge your sobbing. It eventually becomes tiring. And then there is numbness. Nothing but the sickening feeling of not knowing what to do or why. Just the profoundly peculiar sense of knowing nothing about where you are, how you got there, or what you can do about it. At the same time as being severely uncomfortable and wishing it would stop. Not painful. Just nausea.  Similar to the spins. Except lying in bed hungover, you at least have the bed beneath your back. This is like the spins, with nothing at all to hold onto.
