The dream.
Psychedelics are about changing the dream that you're in right now. That's about it. Oh, you don't realize you are dreaming right now? Well, consider this: When you are sleeping at night, and you have a dream in which you are engrossed in, is there any question about the realness of said reality? No. However, what happens when one becomes lucid in a dream? When one, wakes up in the dream, and realizes he is "of" the dream, but not "in" the dream. Well, one is no longer scared or concerned about what is happening in the dream when one is awake in the dream. If anything, a lucid dreamer will become more fearless and curious to explore that realm. If a 'person' were to approach you in said dream, while lucid, and said "The world is ending! The world is ending!" then you would only laugh and respond in a way which is appropriate for you knowing this is all a dream. So, what makes one think that they are awake right now? Have you woken up from this dream? It's an unmistakable event if it's happen to you, in other words, you will know it. The perception in sober 'reality' is shifted, so that you are now "of" reality, instead of "in" reality, just like lucid dreaming.
The difference between the nightly dreams we have, and the dream we're all in we call reality, is that the dream we call reality is very stable in illusion. Imagine in a DMT trip, if suddenly you had a body, with legs, arms, and you were there for a long time, and you everyone else in the trip was behaving predictably most of the time, it could fool you completely into thinking that you "are" that body, and the thoughts it was producing. Really, it's just another experience that the dreamer was having, just like the one it's having reading these words right now.
DMT quickly and dramatically, changes the dream, for the purpose of showing you that you are in one. However, most of the time, we don't catch this. Instead, we just think about where we went inside the DMT dream, instead of the fact that the only thing in the universe, the "watcher", didn't go anywhere, it just watched the dream change to hyperspace. It tuned into a different station. Same viewer sitting in the same seat, different bucket of popcorn, different movie. And we all know, the DMT hyperspace movies are really cool.
So what's the problem? Why can't you see that this is a dream? Why does it feel real to you? That's because you've forgotten who you are! So, I ask, who are you? Not the name your parents gave you, or your life situation, or the events that took place in your life in the past, or what someone told you, you were, or what you read that you were in a book, or a list of qualities you've experienced yourself having demonstrated recently. The "who you are" is the real question, and since it's unanswered in your life, you attach to ego which gives you a nice little identity which can provide you with all kinds of circumstantial information about your life situation, but not who or what you really are.
The fact that you are reading this and have probably taken DMT yourself, gives you a leg up on the next guy if you can see DMT for what it is. The "who" you are can be partially danced around while on a DMT trip in hyperspace. If you've noticed, the "Camera" in which you seem to be observing reality through, right now it's positioned between what seems to be a human head, and in a DMT trip, it's just smack in the "center" of your experience and locked in. It doesn't move! You're always right there, "watching" everything, from this fixed point of view. No matter what, you are, and will always be exactly at the center, watching, in life, in trips, in death.
You see, you are not the things you see in a DMT trip any more than you are a human head or even a human brain. You are what is watching the brain, or watching your thoughts, or watching what you see. You are only the watcher. You are the still center of it all, no shape, no form, not moving, just still, watching. The thing is, I can tell you what you are all day, it won't help you to really know who or what you are. You must see it directly for yourself.
The important part: When one does awaken, the first thing realized is that no person awoke. It was all of reality, which has awoken through that person. So, reality, has awoken through me and now I can tell you so. This is about the best an awakened 'person' can say. Put another way, the dream woke up to itself, and realized it's looking at itself through a person.
Notice when you come back from a DMT trip, you feel like you are falling back asleep from a more wakeful state. Falling back asleep into the dream of humanity. However, once reality wakes up through you, it no longer feels this way. You don't wake up more when you go to hyperspace, and you don't fall asleep when you come back. Instead, you have the very real sense that only the dream is changing, no waking up or falling asleep is being done any longer. That part of the ride is over. Reality knows itself know and can no longer hide in this way.
There can be a sense of Oneness on DMT, that's because 'we' in the dream, are just ONE dream. There is one dream being had, and YOU are the one having it. All those problems you have in your life? You are dreaming them. You're playing all parts, all roles, simultaneously, but you're experiencing it all only through one perspective, one camera, one 'person'.
Reality is layered like an onion.
1. We are human beings, with or without the notion of a "soul".
2. We are the one and only dreamer, watching the dream of humanity through one human.
3. We are ALL, collapsing the watcher and dreamer into one, creating pure experience.
Most people walking around the planet appear to be at layer #1. Successful in our "lives" or not, we go around thinking about how well we're doing, or how badly we're doing. We plan for the future, and think about how to "get ahead". We get really upset when things break, like our cars, or when we lose relationships with people we don't want to.
A few people on their way to awakening, get stuck at #2. They become detached, realizing they are the watcher of the dream. It's a very powerful place to be in relative to layer #1 because in nearly any situation, you can detach and realize you are observing. This is a somewhat dangerous layer to spend too much time in as you are constantly aware of the emptiness of the universe. It can lead to getting trapped in meaninglessness, and can even result in depression.
Eventually, the dreamer and the dream collapse into one. There is no more viewer, watching a target. Instead, it's just the experience itself, as one-ness, experiencing itself. When this layer of knowing is realized, then balance is restored and the dream no longer feels so empty.
Awakening brings understanding. It brings truth about reality, not what reality is about, but what reality actually is. Buddah called it the "Crossing to the other shore", a different place to which view everything.
Jed McKenna woke up many years ago, and began teaching about awakening, if you want a fun, easy to read book going into more detail about what I'm rambling about, try this:
