You find yourself talking to a friend about Inception on the phone, as he continues the conversation you remember more about the time you guys saw it at the cinema, when it first came out.
Then you remember how you only recently watched it at home with another friend, not this one. And when you were watching it at home you also remembered watching it with the first friend, who's talking to you now.
You are discussing the plot when suddenly the sofa you're sitting on begins to crumble into dust.
The dream is collapsing.
Your friend tells you to stay calm as you prepare for the kick.

...
You awake with a start, pouring popcorn on your lap and turning to a friend on the right who is laughing at the fact you fell asleep in the cinema.
DURING INCEPTION.
The year is 2010.

BWOOOOOOM.

You set up infinite mirrors and one of the mirrors strobes itself with a screen playing Inception on the other side. AKA You watch yourself watching Inception ad infinitum.
