After a high dose of DMT I learnt

You didn't learn anything. Your brain was firing off randomly and you tripped balls for a while. I haven't tried DMT, but I have tripped on shrooms and acid, and even though other people I know claimed to feel more "enlightened" afterwards I saw through that bullshit and realized I was just high out of my mind and hallucinating hardcore. You don't learn truths when you're using psychedelics. It's just garbage.
People like Terence McKenna are the worst kinds of people. Using drugs does not make you some sort of divine philosopher who knows more than everyone else. You're just a druggie who has seen some cool (but meaningless) shit.
