I think it might be a reference to the AHI number with which medicine marks the boundary between normal respiration (AHI <5) and sleep-disordered breathing (AHI>5).
That would be correct, compared2what?.

In SDB medicine, to qualify as having an SDB "event" you must completely stop breathing for a minimum of ten seconds. Shallow breathing doesn't count.
If you stop breathing for "only" nine seconds, that doesn't count as an SDB event either.
Equally, If you stop breathing for much longer than ten seconds, say, perhaps over a minutes (and I have had such long-time SDB events) that isn't weighted any more than a ten second event.
To be officially diagnosed with Sleep Disordered Breathing (SDB), you must average more than five of those (ten second and over) events per hour. Thus, SDB = AHI >5.

In my case, I averaged over seventy events per hour, or more than one (ten seconds or more) event per minute. Many of my events lasted for twenty or thirty seconds, some for over a minute.
Once my blood oxygen level dropped beyond a certain point, it was considered too dangerous to conduct the test any further, and I was awakened from my sleep by the sleep lab technicians.
At home, of course, typically there is no one to wake me, although, my wife Ronnie will awaken me if she shes me stop breathing or struggling to breathe for extended periods of time.

I'm not sure that this is the right way to put it, exactly, but I find/found it so terrifying that it's difficult for me fully to credit the proposition that I survived it, although in rational terms, I know perfectly well that I did.
I very much hope it's not that rough for you, though. Of course. And (of course) you have my deepest sympathies, regardless.
I am fifty-six years old, and have led a full life, and regret nothing. Many people suffer from severe SDB, so I'm hardly alone. My wife has bravely struggled with cancer for over twenty five years, so my problems seem quite trivial to me by comparison.
However, normal sleep (and dreaming) is by now completely alien to me; it's become a pipe dream of a pipe dream, so to speak.

At some point, my body and mind simply refused to go to sleep, and I spent a full three weeks wide awake.
For me, it is difficult to adequately describe what it is like to live in terror of falling asleep for such an extended period of time.
As the days go by, you begin to hallucinate, to quite frankly, go a bit insane.
You try desperately to go to sleep, but by now, your mind will not allow it, I guess some part of the brain realizes that you are being, in effect, suffocated to death when you sleep, and in my case, my "brain" or "mind" simply refused to let me sleep.
After three weeks, utterly exhausted and nearly suicidal, I took heavy overdoses of alcohol, prescription anti-anxiety and sleep medications, and literally hammered myself to sleep in the safety of a controlled sleep lab setting.
Until recently, I was thoroughly addicted to heavy doses of the above medications / liquor (plus a handful of over-the-counter sleep medications) to get any sleep at all.
The xPAP therapy has literally been a lifesaver for me, and the friends and advice I received on CPAPtalk, a life-raft in a nightly storm. I cannot recommend the place highly enough if you suffer from SDB.

I'm especially interested in what physical or metaphysical framework you think might make such occurrences possible and real, if indeed you believe them to be.
Anyhow, welcome.

Thanks, Simulist, I will do my best.
Because I, my wife, and my friends in medicine and the sciences are hard-core believers in the scientific method, I summarily rejected any possibility of "extra" or "super" natural explanation.
Quoting what I initially wrote to Mr. Rupert Sheldrake:
"
I have had a number of what, for the lack of a better term, I could characterize as "predictive dreams". I must emphasize the word "could" in that preceding sentence. There are dreams by what I categorize as "push" dreams, and dreams by what I call "pull". I can elaborate on these self-coined neologisms at some other point, if you wish.
Despite these odd dreams, I must caution you that I am not a fan of paranormal "science", for what now I trust you can understand to be obvious reasons.
The world population is expected to hit seven billion later this year. (1)
Subtracting for children under the age of ten, this still leaves many billions of people old enough to reliably relate their dreams to others. (2)
People dream 365 days per year. During a normal night of sleep, humans usually experience about four or five periods of REM sleep (3)
Using 5 billion as a "spitball figure" of humans over the age of nine, the math would be as follows:
5,000,000,000 (guess-estimated number of humans 9 years of age>
Times 365 days, equals:
1,825,000,000,000
Times a conservative estimate of four periods of REM dream sleep equals:
7,300,000,000,000
That gives us an off-the-napkin number of seven trillion, three-hundred billion dreams per year.
With such numbers, that someone is bound to have a number of seemingly "predictive dreams" is almost a given.
I hope you see that my point. While perhaps not as exciting as the concept that I can actually dream of the future, the likelihood that I am just a freak of statistics seems to me to be altogether quite reasonable.
Thanking you for your time, I remain,
Sincerely Yours,

I must apologize again, but my concentration is often poor to nil, and I have to strictly limit my time looking at a computer.
I will try to get some sleep and post more later tomorrow.
