Physics..

Last night I projected to a home (yes, with permission!) and it was dark in one of the rooms but could still see the red carpet and a twin size bed.  My friend suggested the room was totally pitch black. How could I possibly have seen this?

So....

Having visions of super-relaties?

Check.

Having a perspective in a location far remote from your body?

Check.

Vision a little bit better than usual?

That is a no-go, lol?

Seeing in the dark should be the least difficult part of this story for a normal person to accept 

The short of it is... you just aren't constrained by the same rules that apply in physical reality in general... this should be obvious from the act even being possible, if you think about it!

When you spend time in a place, you build up a mental picture of it - the "map" that allows you to walk confidently through a dark room in your home because you know where all the obstacles are.

That mental picture has an astral reflection, which projectors can see when they're Out.

The fact that the room was dark didn't matter: Your vision wasn't based on available light, it was based on the astral reflection made up of what people know is in that room.

And through those couple paragraphs you have answered the question "what is the RTZ?"

Those "mental pictures" can and do overlap too... that is what we call reality fluctuations

Anyway, please continue, I just wanted to point that out.
