In my own 'dimensional' travel system, I do not project consiousness, but rather just awareness (senses). This of course causes dual awareness streams in the physical brain system. I can do it while awake or asleep and do not have remembering problems.

It sounds a bit like what the shamans call "journeying". For them the dual awarenss stream is also usual and gives them the abilitiy to report what they see while it happens rather than afterwards by memory.

I never read about your places, though. But I am no expert. I just went to the "lower world" via shamanic journeying twice and have no idea how the "upper world" might look like. Both times I was fully aware of both the journey and the physical plane the whole time.
