Yes!

That's how it feels to be back amongst the living. I knew as soon as I awoke that I was better. My head was not as woozy and my ears were almost unplugged and the slight headache was only present when I blew my nose.
Two days ago I almost posted a blog on breathing - I knew only the absence of it at that time and was longing to breathe through my nose. I had a nanosecond of panic when I thought I was out of Breathe Easy strips - little strips that pull your nostrils out and help you breathe through the nose as you sleep.
I read in a book on yoga a few years back that you breathe through one nostril at a time. Something like a 90-minute cycle on one nostril and then the next cycle on the other. You were supposed to become aware of the cycle and control it, if I remember correctly.
I am thinking that if that is true, then you might be oxygenating one side of the brain when you breathe with one nostril and the other when you breathe with the other. Now, how does that affect your dreams? Are they more creative when your right side is oxygenated? What about if you are wearing strips? Does that affect the quality of your dreaming? Of your sleep? So much research to be done still...
