Well funnily enough I had one in the week (perhaps there's summat going round) and I was sufficiently frightened to be far too scared to close my eyes. So I got up and read for 2 hours until I couldn't keep my eyes open any longer.
But I thought after, why didn't I test? I could have been hypo, and then had a liver dump which caused my morning high BG?
We'll never know.
And I can't remember the last time I could remember a dream, though I used to, rarely bad - just unfathomable where I'd be somewhere and there would be people from another part of my life there - eg work people's other halves, who I/we only knew fleetingly, at my best friend's house or whatever.
Anyway, it's Vewwy stwange.
