Then I'm standing in a long green corridor, smooth concrete walls painted pale green, like seaweed.
The floor is sand.
Nothing but sand and pale green expanse stretching for miles, apparently in both directions.
Nothing but a square shaft of white light shining thru a window apparently miles from where I stand.
This soft sand is going to be a bitch to trudge through and it is a bitch, keeps giving way and is hot, painfully hot and sinking, just like walking on a beach.

I walk for so long and so far, for a year, for miles, but there's nothing else to do.
No sleep, no eat, no drinking, nothing to do but plod along, pausing to scream occasionally;
the white square of light never getting any closer, until one day I pause to scream and, looking up,
there it is: a mirror
with a red creature inside screaming,

clawing at its face
and dissolving into
pink mist
