Swim had a very unique DMT experience that he hasn't had before in his ~25 previous trips. Swim believes that this was the largest dose in terms of amount of DMT he managed to inhale that he has had.
Basically what he did was after inhaling, stand up, then start pacing around his apartment for about 10 minutes. Swim insisted on doing this trip with open eyes instead of closed eyes. This may be the cause. Whereas as closed eyes allow you to take the trip from a 30,000 foot perspective with regard to your life, open eyes forces you to confront your immediate surroundings and makes the trip much much less abstract cognitively.
To describe his mindset seems almost impossible. What it felt like was that everything was wrong. Like all of existence. Swim just kept thinking of the activities that populate human life and looked at them as unbearable. And it wasn't like he was thinking about bad things like sickness or war.
Things such as sleep, bathing, sex, eating, watching television and working all seemed like horrific notions. It really felt like swim didn't understand any of it, or understand what the point was. It seemed like thoughts were coming into his brain at too fast a rate and he couldn't handle all the information. It was almost like viewing human life from the position of a creature that evolved in a different environment. The best way to describe it would be the horror if you found yourself suddenly turned into an ant and realized that the rest of your life would be filled with ant activities.
Everything felt so foreign that swim didn't know what to do, or how to go on. Any possible thing he could consider doing at that moment seemed pointless or repulsive.
After a while it seemed like the flow of thoughts into his brain subsided to a manageable level and he had some unreal visuals. (The period of his freakout he was beyond even processing visual input in a normal way, one of the reasons he thinks he needed to pace was because he couldn't stay in the same room long enough to watch it morph).
Ironically after the experience was over, swim felt incredibly happy. Like he was giggling to himself and thinking how amazing life felt. Maybe this didn't give swim an appreciation for human life, but an appreciation for how we are programmed to appreciate the things that compromise our lives.
