i liked your idea of streams winding about and maybe back on each other. It was such a pretty picture
my own understanding that what we know of as time, 4d IS a constructed phenomena. Partly it is like being in a classroom, to teach us about a concept that might otherwise be hard for us to understand?
as far as not being able to experience 4D for example, I've seen the time tunnels briefly when I was younger (during meditation), so I know I can...
Things like the merkaba might take one there or even beyond I don't know as I haven't been too deeply involved in that...
I should be able to to taste or smell 3D for example and maybe I do, I just am not accustomed to calling that? Words can be silly if I take them too seriously....
all that said I don't know about this gorges thing either... I usually say that but I don't have actual experience it is that way... my reason for saying it is to make it clear you don't get to (easily) jump between parallel streams lol....
