This video shows some pretty DMT like visuals that one would see with eyes closed. Nothing else can compare to how extraordinary it would look though comparatively to within one's "own" mind.
I had some Saturday afternoon and literally thought I broke my brain (again). It's impossible. What I saw was that I was being confronted with a massive energy vortex and nothing else existed. I no longer existed. This was all that there is and ever will be. It was amazing, crazy and frightening all at the same time. Time folded in on itself and seized to exist.
Whatever it is; it is THE shit, ancient knowledge download to your cranium.
Audio was from 1989. Well before "The Matrix" crept into our subconscious.
