I thought I'd share a story about what happened to me yesterday.
I am a migraine sufferer and occasionally, I will get one so bad, I need to take myself off to the hospital for treatment (that only happens a few times a year, thank god).
Anyway, the hospital decided to keep me in overnight for observation (last night) after giving me a shot of Morphine and hooking me up to all these machines (the tests revealed a hormone imbalance and I need HRT now).
Now, Morphine does really strange things to me.
I took particular interest in my blood oxygen saturation levels, which were hovering around the 98-99% and after the Morphine kicked in, I was using Pranayama techniques to try and change it - also, using the opportunity for being hooked up to machines to practice a few recordable Bio-feedback techniques....until the nurse came in and stared being all very stern and 'matron-like', telling me to knock it off and try to get some rest...
I was like 'on one condition - please tell me how low my oxygen readings are going to go when I am in deep sleep, because I won't be awake to know this' (like I said, narcotics make me insufferable). lol
She said 'it will go down to between 88-90% when you are asleep, because you breathe much shallower then, but don't work yourself up too much about it - that's my job - your stats are all normal, so please try and get some rest now and shut that brain off of yours (easier said than done in this environment).
So, I decided to take her advice and try to sleep, or at least try and go into Yoga Nidra (now, doing Yoga Nidra under these circumstances is absolutely amazing), but anyway, onto the whole reason for this post.
I thought about what the nurse said, and decided to go to sleep, but to 'program my mind' beforehand, to wake up just as I was about to enter non-REM sleep (I didn't know how Morphine would affect this), just so I could catch that moment on the machine, while I was still technically in 'deep sleep', just to check my oxygen saturation levels - not that I didn't take the nurses 'word for it' of course.
So, I set that 'mental alarm clock' and yes, I actually managed to accomplish this, and the machine read 87%.
Now, is that 'mental control' or what? I am pretty proud of that achievement. lol
Then I keep thinking to myself now, what woke me up while I was fast asleep? and no, there was no part of my brain that was consciously aware at the time.
