Thanks for introducing me to an older thread! I was an OS (Operations Specialist) in the Navy...US, Navy in case some might wonder. OSs are part of operations, and operations intel. Anyways out in the IO (Indean Ocean) we had this one guy who was talking in his sleep. This is a major DQ/NOGO for clearance. My LPO (E-6) was getting ready for midwatch and heard this guy babbling away. His clearance was taken away in a matter of hours. He was in the kitchen by breakfast.
As for myself, I can be sound asleep for hours and all someone has to do is say my first name "Sar"
or make noise, such as door opening, footsteps and in the next 2 seconds I am up.
Making rounds in the Navy you cannot touch the person. You can call their name shake their rack (bunk). I am awake from a deep sleep long before...with the sound of footsteps, or with my curtain sliding open.
From a deep dream / REM shouldn't take long to be on your feet and moving.
HOO YAH NAVY!
