I never can, though that might be partly because they generally occur
on muggy nights where it's hard to drop off anyway.

Apparently I used to, when I was a child. Can't do it now, cos I seem to
wake up just before they arrive, probably my subconscious saying "There's a
thunderstorm outside. Get up and watch!" )
