Death

He was so tired. He lay there in his bed, laboring for each breath, struggling to focus his attention. His family was gathered all around him, some of them with tears in their eyes. Daughter. Son. Three grandkids. A flicker. An electronic sound snatched his momentary attention, then he lost it. Thinking was so hard. Being was so hard.

Then all at once, he fell. Not from his bed or from any physical height, but from himself. He slipped right through his own body as every dimension collapsed on itself, and he accelerated away into... where? It didn't hurt, but it was terrifying. Like skydiving, but with no sky. For how long? It was impossible to tell. It could have been a thousand years already, or a split second. He was free falling through reality itself, unsure if he would ever find his footing within an embodied existence again.

This is death. Not the termination of consciousness, but the collapse of spatial experience.
