Help Me I'm Falling

I know everyone has probably had this happen at one time or another. You crawl in bed, thoroughly exhausted, dose off, and are suddenly awakened by the sensation that you're falling. This has to be one of the most startling feelings, and when I realize I'm OK, it angers me because I was awaken. This action of feeling as if you're falling during sleep, is called a hypnic jerk. There is no scientific answer as to why this occurs, but there are a couple of theories that seem to make sense. When you have dosed off, there is a time where your brain is still somewhat conscious of your surroundings. During this time, a noise or a touch can awaken you because your mind is still working on overtime, while the rest of your body has had a bedtime story and is on its way to sleepy time. At this moment, your heart rate slows, your body temperature drops, and your muscles relax. Then the brain kicks in, and tells your body that you're losing control, you better get off your @$$ and catch yourself! Thus the jerking motion that wakes you, and your spouse up. Now, not only am I mad for waking myself up, but she's mad for waking her up too. I wonder if this explanation at the time of me disturbing her sleep would make sense and diffuse the situation? But honey, It's not my fault, it's... my body and brain's fault. Yeah, that should help. I'm just glad I'm not one of those people with unlimited amounts of energy, like they've eaten the Energizer Bunny for breakfast. I could just see my brain telling my body to 'drop and give me fifty'.
