The Awakened Viking

That could just be an effect of a mechanical society suppressing a higher consciousness that is within everyone. Once a human being surrender and flow with everything, creativity naturally flows out of it as well. It might not be Picasso quality art, but creation nevertheless. I've worked in kindergarten, and NONE of the children had problems creating through the different artistic activities everyone participated in

If you're just stuck in a mental loop of thoughts and going exponentially exhausted/crazy, you could try to "lose yourself" in some videos. Unlike video games, which are interactive, watching something requires very little input, interaction and energy from you, but at the same time it can catch all of your attention. - And yes, I get why you want to come back, this "mundane" physical reality might not seem as colorful as a successful deep DMT trip in the beginning. But physicality, consistency, limitations and the illusion of time are a few of the greatest aspects of creation. In "DMT-land" you are shown raw pure creation coming out of nothingness with infinite potential to be anything, constantly flowing into infinite new possibilities. But the consistency of this universe is one of the most magical and beautiful parts of it, it gives creation an opportunity to make tiny stories with meaning for deeper entertainment. You can see a tree on a hill, take your time to walk over, have even more time to touch and feel every single leaf. Have children and watch them grow and experience with the story of them being the same being. Create worlds with trillions of cogs and beings interacting with each other. Existence being a gallery, the limitations of this universe gives us the opportunity to create a type of art only possible through this separation and limitation. Hopefully you are not so out of your mind from exhaustion that you can't finish reading a sentence without forgetting what the beginning of it was

I don't think this is about a lack of melatonin or other mechanics that make us fall asleep naturally. His body literally thinks its going to die and shut down if it "loses" waking consciousness. Existential crisis similar to the first time you realized you were going to die as a teen, just my humble assumption

You didn't write that much about the trip itself, but did you breakthrough and die, merge with the source/"went back home"? Maybe you just need to accept dying. If you really haven't slept for 4 days, and it continues, you are probably going to get so astronomically tired that your ego just gives up and accept it on its own, everything will wash away and be gladly "sacrificed" just in order to rest. Even if you're not into deep spirituality or have ever taken psychedelics, I think everyone can relate somewhat to being "beyond tired" and letting go of whatever they "have" to do in order to sleep. And what's going to happen is that you will accept the idea that you will die, fall into sleep.. but then suddenly you wake up after 15-20 hours as a human again and realise that your body doesn't just shut down because you had an existential realization/aha-moment. And if you become God, you are free to choose whatever, go back to the source or come back and continue to experience this cosmic gallery from the perspective of this current body and ego of yours. Existence is a garden and gallery, and you're just a flower that need to flow with whatever natural forces that are around like a strong wind. You could of course tighten and harden your stem, but eventually you're going to break and surrender anyway.

If I were to keep it short and mention just one thing, it would probably be the absurd levels of open-mindedness. Where else in your life/society can you bring up ANY topic and be met with questions rather than a spot on the gallows. Although they won't kill you literally, many might try in other ways And lots of people would start civil wars and hang each other, even today, if it weren't for certain ingrained norms and laws, however shallow these rules might be.

This kind of "neutral spirituality" is deprogramming. There is no holy book. So whenever Leo, Alan Watts, Adyashanti, or anything Zen'ish actually speak, they are pointing towards what it is NOT, then you point and observe until the only true thing is left
