That could be a whole new technique!
The only thing is, would you be able to hear it in your sleep ( in the dream/REM stage? )
Yes.
Since your ear doesn't close itself off at the pinna or anything of the sort during sleep, there is nothing stopping you from recieving auditory signals. The thought may be that your brain will not acknowledge or recognise these auditory sounds during sleep due to the difference of neurotransmitter production, but you still receive auditory information.
Since the the basiliar membrane carries information to the spiral ganglion, to the auditory nerve, which then comes all the way down into the lateral lemniscus within the brainstem, the feed of information is not itercepted by lack of any chemical production of the sort. The signals are still processed up to the medial geniculate nucleus (MGN) within the brain.
This is what is responsible for incoporating outside sounds into dreams and for quick awakenings by loud sounds. Sounds are still recieved, thus the brain will integrate it into the REM activity. When you hear a loud sound (or a sound that is out of the ordinary pattern of sounds you initially fell asleep to) your brain picks up on this. The dorsal cochlear nucleus within the brain stem is responsible for filtering out and differentiating sounds (right before the lateral lemniscus), thus, when there is a disturbance within this systematic stream of information, it activates the residing reticular activation system (RAS) which is, essentially, responsible for waking you up.
Sometimes the overwhleming flow of chemical (norepinephrine and other monoamine transmitters) will cause a rush and cause that jumping sensation.
That's it explained rather roughly. Those of you who have studied this as well will see my rough-edges, hehe.
Hope I have been enlightening.
