I appreciate this. As one who walks between worlds, I too have had a difficult time from childhood to now living in this world. It is hearing without hearing, seeing without seeing, knowing without the structural constraints of knowing. I also have PTSD, and have had before it became an ‘accepted’ term. I do some work with ex-combat vets because of what they ‘see’ and ‘hear’. I don’t believe it is illusion — nor hallucination. Many of them have become, in my opinion, spirit walkers.
