I don't hear loud explosions, but sometimes I have periods where the voice in my head (the inner vocalization of thoughts in my mind) is yelling at me. So instead of "I should go to the grocery store after work today," it is "I SHOULD GO TO..." It is odd.
I died in my dream once. It was pretty scary. Car breaks, I go through winshield, slide across pavement, look back at the car, and another car hits me head on. I literally float up from my dead body and look down on it. Then I wake up. Freaked me out for weeks. To this day I remember every detail. Usually I wake up when I trip and try to catch my balance in a dream. No gun shots tho'.
My wife says I snore with explosive force if that counts. I think I may have whatsitcalled....sleep apnia or something like that. They say you actually stop breathing at points. JuanValdez maybe that's what your wife's got (unless you're sitting on her chest when she wakes up and accuses you of trying to murder her).
