To answer the topics subject; I think we do, althought I would NOT label it as the "GOD-LIGHT"!

IMO people are far to fixated with the "light" side of DMT, personally I almost prefer the darkside's tutoring, even though the experience may be completely horrifying, I'm always able to bring back so much more from it.

The "light" usually blinds and dazzles me with the most amazing and confounding experiences,  the "dark" side of DMT however, doesn't fool around with me, it gets right down to business, no seat belts and bandaids.

The problem, I think, lies within peoples genuine fear for these experiences and entities, even though these entities and space's may be mindbogglingly profound and dreadful this is not what's arrests your attention, but it's the sheer emotional distress and fear that's arresting your attention and disables your cognitive abilities.

I say: Don't be judgemental in your perspective of these different experiences, that's in essence what makes them difficult to learn and integrate from in the first place.

Some experiences may want to gently dissolve you before taking you with them, other experiences will simply devour you through mastication

Regarding your statement:    

Only once have I felt as if "time is short" and things unravelled in a hurry like in Alice in Wonderland - Tea party style.

Most of the time I feel as if I've simply been reborn to live a new life, there's no thought of another "real" universe, no memory of it either, I'm simply there.
