I hate to state the obvious, but you
didn't pass out... which I would have thought is a good thing
Sounds like you have excellent control and good hypo awareness - which do seem to go together.
Consider that the BG level shows the Glucose available in your blood and not necessarily the current state of your cells which need to use that Glucose - so in the same way that an untreated Type 1 can have a very high BG while the cells are starving for energy, you could have just given up your last dregs of Glucose to your cells and thankfully caught it in time
