Nice post. I do feel like vibrations we sometimes feel while WILDing or OBEing are representation of our bodies changing vibrational frequency, so we can "visit" planes of existance of that frequency.

And I think, that dark matter is those parts of the world that we don't see. Like right now, we are in physical and that's what we see. But everything in physical has it's counterpart in other planes, and all of those planes can be of different density or vibrational frequency. Physical is like the tip of the iceberg that's visible to us. Rest of the mass we see only if we change our perception.
