Angels unawake: Dreaming in Different Cultures

I'm not alone in noticing, vaguely, that the Bible has a not insignificant amount of revelation by dream going on. Nor am I alone, I imagine, in thinking how utterly unlikely that seems to occur in my experience. And now, for the first time really, I've found something that feels like it might get somewhere closer to making spiritual experience in dreams seem more plausible. It's here: To Dream in Different Cultures  and the interesting question it poses is this:

the intriguing question is whether different sleep cultures encourage different patterns of spiritual and supernatural experience. That half-aware, drowsy state is a time when dreams commingle with awareness. People are more likely to have experiences of the impossible then. They hear their mother, many miles distant, speaking their name, or they see angels standing by the window, and then they look again and they are gone.

it kind of chimed with my more recent experiences of being between sleep and wakeful. And, come to think of it, such experiences as I can recall from childhood. More recently, I've found that I might be reading before sleep and my tiredness is such that I start to fall asleep at the book or screen. But, the strange thing is to find that somehow my slide into sleep has become a slide into reading a dream book almost identical superficially to the one I am reading, yet, when I wake after a few moments (minutes?) I realise, was saying something entirely different from what the author of the book in front of me wrote and had printed. I have vague recollections of some interesting ideas for plots or takes on my recent life being the subject matter of these dream paragraphs.

As a child, I recall a few times of dreaming in that time between being asleep and waking for the day; one time so vivedly did I dream of a cap-gun under my pillow, that I was a little bewildered to find on waking properly, that the toy was not there after all.

So, to consider a time when 'dreams conmingle with awareness' now becomes  imaginable to me because I recognise the experience -I think.

But this doesn't necessarily help with such things being revelatory or spiritually significant: my cap gun seems not particularly so, for example much though it reveals something of my desires at the age of about 6 years old. And yet, if we do wish to claim that in some way the processes of reading scripture, giving attention to God, reflecting on our inner and outer lives, sharing our lives and being immersed in rituals does genuinely give us insight into God's communication with us, then these hemi-conscious states are not ruled out from being part of the mix. Indeed, since they seem to be plausibly times/places where our desires can be manifested in some way in a visionary sort of way, it seems plausible to me that they could re-present to us some of the processing our mind-brains may have been doing in relation to our spirituality.
At the very least.
And if God does, perhaps, sometimes, somehow get involved more unmediatedly in the business of mind-changes (with all the implications that would have for having some physical effects on neuro-electro-chemistry even if via a top-down causality mind-to-brain), then perhaps sometimes these visionary moments may sometimes be God-touched.
