This is actually more common than you might think. (Just be sure not to expect it to happen) It may be slightly more predominant with some wilds, but can happen also mid dream if you manage the situation and prolong afterwards, or at dream end. One thing that might help is to start expecting for the surroundings to reappear and distinguish contours in the darkness and even if blind to act as if nothing has happened using your other senses. The dream has to return at some point.

We also have a podcast on this:
