How about the opposite kind of reaction...
I woke from a dead sleep one night, and i could distinctly hear my son getting into the Oreo cookies in the kitchen. He had a history with Oreos, and i knew exactly what that package sounded like. Well, at 3:30 am he just wasn't allowed to eat Oreos. I wasn't alarmed in the least, just a little irritated.
So i got up, stumbled slowly into the kitchen - no Ryan. The crackling was louder though. Why was the room orange? Holy crap - the house one house away was burning like crazy! I ran back to the bedroom, told my wife to call 411 and leaped down the stairs while pulling my pants on. Of course, i meant 911. Fortunately she knew that.
I got there in time to pull two elderly neighbors out of the downstairs window, and with 2 other guys that had just shown up, catch the lady jumping from the 2nd story. Trust me - don't try that. She flattened all 3 of us.
Anyway, i didn't pull a gun on the neighbors or anything. But was darned glad i was a light sleeper. You never know - one of these days your hair-trigger nerves could save your life.
