Journeys through Spacetime

Rather late but...

Relevant Part:

I gazed out the window aimlessly in an endeavour to ignore the massive crowd enveloping me...
Suddenly it clicked. I became lucid. I attempted to fly through the window, but failed, instead bumping my head.
I strived once more after reaffirming my lucid state. I had 10 fingers on one hand!
This time I succeeded and after a brief float through the air, I landed myself on a vibrant green lawn.
After an unsuccessful attempt at remembering TOTY, an elderly man suddenly appeared beside me.
I remember the TOTM and ask "Whose dream is this?"
He thought for a while, and then responded "Yours, mine and his in truth"
