Some people have referenced the place we call sleep and dreaming as being awake. There are messages from dreams, ultimately understood as Self communicating with self.
We don't always remember what we dream, and even our ability to recall accurately can be misconstrued. But there are moments of clarity that often inspire.
It's a practice to develop your concentration, and an ability to be awake in these other realms.
Now is all we have. Namaste Brother.

I suppose that awareness is important in all aspects of our life. Especially since we practice it in meditation. Yet I wonder, is there a time we really need rest from all the minds activities? I have found that constant concentration can also be exhausting.
