IF you fall asleep in your dream you die

which is why I'm always falling asleep in other people's dreams.

I sneak in, unnoticed and climb into a bed. 

If you dream a train is coming 

and you're tied to the railway tracks

I'm probably using a jumper as a pillow against the window.

If you dream your parachute hasn't opened and you're falling

I am in a cottage near the airfield. I woke up,

went down for breakfast but then decided to go back up to bed.

If you get a gun out in your dream you are probably 

doing gun fingers in your sleep, mouthing Tarantino dialogue

while I'm in the bunkbed above. 

The cellmate who won't stop snoring.
