Since I was a child I've been drawn to heights. Whenever I saw a mountain cliff, railings on high buildings, I had the urge to go and stare downwards, picture myself falling, and a strange urge to jump.
Even though I've looked pretty damn well down the rabbit hole, on 5-MeO-DMT, I still get the same urge to look again. Boredom has always been a bigger problem for me than fear. And once you see it, you cannot unsee it. You can push it in the back of your mind and it will leave you alone, casting only an evanescent veil over your reality. It will sometimes appear in dreams, flashbacks, and I have a feeling it will appear again in full clarity when you die.
The only direction you can go is forward. Open your eyes and plunge in until you come out the other side. That's what I am trying to do. And I have another hunch that if you manage it, you will come out enriched with the power of the other worlds.
Mind you, this fearsome alien world only appears to me on dissociatives, especially 5-MeO-DMT. LSD is nothing but light. This one I really don't see myself ever quitting.
