I used to vibrate the windows I snored soo loud !! When I was younger and still living at home, my mom would say there was a snoring contest between me, my dad and the dog. She would win some nights. I hardly ever snore now, I use a CPAP for sleep apnea.
My ex girlfriend would just elbow me and tell me to roll over. No harm no foul really. BUT she would grind her teeth. Nothing worse on the face of the earth then a teeth grinder. That would make me give her a nudge and tell her that she was grinding her teeth.
Back when I was an EMT, we had a bell that would ring certain ways for our station and for what equipment was needed (engine, ladder, rescue) So you got "programed" to listen for you bell series to ring and then get up and grab your dispatch sheet. At a BBQ, on of the ladder guys feel asleep in a chair. We carried him next to the pool, banged a piece of pipe the number of times for the ladder crew, and watched him get up and walk right into the pool !! Hindsight says, damm he could have drowned, but it was very very funny when we did it!
