I went back and read some of the Joebono threads for curiosity of what seems to have become legend. My first impression so far is that fear crept up on him. It crept up on him to the point he was struggling to contain it.
Honestly though, I've had a few seriously tough trips where everything was broken and I was gone, and I came back in a completely stunned state. But as the drug wears off I always remember how much trust I have in my own physiology, and in the stability of the neuron. That's one thing that's helped me so much in the realm of philosophical understanding of emotional extremes, and their transient nature, and how emotions leave behind signature memory traces. Try waking up after being in a coma from a failed suicide attempt to find how rapidly your world changes after that moment, and the idea of hyperslaps and returning to reality unchanged with healthy and normal physiological measures is not a big deal at all. You walk it off. It's no big deal. Just don't freak out in your mind and everything is good.
Pardon me if I've taken a wrong turn in this thread, but what I think is BS is fear. Letting fears take your life in the wrong direction is the only true BS. Love is truth. If you can fill your life with genuine love, then nothing else matters. Details will always be details. Fears challenge your ideas of what's real and what's not in spooky ways, but at the end of the day fear is just an emotional sensation to be avoided. Embrace its presence and watch it vanish, I say. To accept fear in your life over living, dying, or anything else is the only BS that exists, in my humble opinion.
