Perhaps it isn't just where I've slept as much as my ability to sleep anywhere anytime in almost any position at the drop of a hat. As for snoring, mine became thunderous during the latter half of my last marriage. Alas, I also developed the curious habit where I'd stop breathing in the middle of the night for what my former wife said was "way too long", which brought her bolt-upright from her otherwise sound sleep. This, for some reason, caused her to punch me in the middle of my quietude while hissing at me to "Breath, goddammit!!!" I never understood why my peace and serenity drove her to such behavior. Also, re-entry is a bone-jarring bitch.
My neighbour used to sleepwalk, one hot Summer, he found his way into my house. THe next morning I found him in my understairs cupboard. I screamed so loud, it frightened the life out of me. I am sure he had a wee in the Cornflakes?
Once on a summer holiday after a night of serious drinking I and two buddies decided to crash on the beach. We built a fire ... okay we're guys and guys gotta have a fire at night on a beach. What we didn't know at the time, not that it would have mattered given the state we were in, was that it was a popular beach. Next morning I woke up thinking :"Shit, this fire is getting too hot.." Only it wasn't the fire but the sun beating down on us. When I opened my eyes I found that we were surrounded by sunbathers!
