First few attempts I got really intense open eye visuals and when closing my eyes it feels as if I'm inside a tunnel of folding colours. This is usually the part where I'm starting to struggle to breathe, even if I remember to breathe.
I can't really feel that I'm breathing which makes it really hard and there are times where I get into a semi-panic because I feel out of breathe. At this point I also put down the pipe in order to catch my breathe and calm down and never continue with a breakthrough. Any tips on how to attain said breakthrough?
DMT breakthroughs are unusual for me... I am never propelled into hyperspace (even when smoking around 100mg), but I must will myself there when the path reveals itself. Even with the chrysanthemum chandelier looming above, I still must do the work to move toward and through it... so maybe my method for doing so can help you.
First off, you must remain with the firm intention of getting to hyperspace. The "direction" should be apparent (whether there's a crystal crysanthelier, a beckoning figure, approaching hallucinations... you know which way I'm talking about, I'm sure.) Move in that direction. If you have done much spirited running or martial arts, you know to move your
soul, rather than your body... I'll mention more on the "moving" later.
You should have enough of your facilities about you to do so. If your ego or semantic hardware is going to sluff off, it will do so after getting there, no worries. Just keep going that way.
Key to this whole process, and to coping with the lack of breath, is the practice of pranayama or "mindfulness of the motion of the breath within the body". I'll spare the explanation, as Alan Watts does far better than I ever could in
this video.
Try it out, and you'll notice that there is [/i]something there[/i]... literally it is the right half of the language center that you're amplifying and experiencing in doing this... not the part that makes english and plays mary had a little lamb, but the part that handles the nuance, connotation, emotional content and semantic underpinning of english and music, the part that "feels" sound. This portion of the brain is the inerface of Broca's area (language forming) and Wernicke's Area (language processing) through the angular gyrus (the middle portion that links all your senses and allows you to, say, close your eyes and visualize a matchbook in your hand). There are two halves of this system, linked in the center of the brain. Tim Leary called these two halves the Neurosemantic (4th, Left) and Neurosomatic (5th, Right) "circuits", as you may be familiar with them. This area is where most of our narrative thought comes from, and is likely the loudest voice in the symphony of your head.
As a practical, feeling-based example, since music is also handled partly by this area... The melodic, articulate machinegun repetitions of Kenny G tickle the left half almost exclusively, while the soulful wailings and modal dancing of Jimi Hendrix reaches deeper, to the right half of this system as well. This is why his music seems to touch the soul, because it comes from *feeling*, not just technique and thought.

So the general jist is to grab ahold of this part of yourself before you even touch the pipe. Let the in/out effort of your breath fade away, allow it to just happen as it will, moving along with it. Once you have hold of that "5th circuit" rapture, and it remains constant throughout the cycle of your breath, take your toke(s) whenever it seems right. I find that it's best to smoalk as much in the first toke as will allow me just enough capacity to take the second, which is usually a BIG hit that's guaranteed to do the job. Three tokes simply takes too long for me, and the opportunity for breakthrough is gone before the breakthrough dose is achieved. Then again, my tolerance is rather high...
The Hindu texts hold that this neurosomatic rapture is the first step and the way toward the higher states, and I find this to be true in a shockingly poignant way... As the trip sets in and you feel the "pull" toward the breakthrough, join the feeling of the breath within you (which you're still mindful of, right?) with the will to go in that direction, turning the two things (breath and breakthrough) into one fluid effort, like a perfect backflip. Use the power of your body's tendency to breath to keep you going that way by moving with it like Mr. Watts describes.
Now, at a point (usually somewhere in the "tunnel", as you have said), you will experience the feeling of not being able to breathe. This is normal, do not allow your alarm to disrupt your one-pointed effort. Instead, take stock of the situation. You'll notice that the in/out of your breathing has in fact stopped (rather, your mind is moving so fast that you are just "in between breaths" for a very long time)... BUT, that deeper feeling of breathing is still there, and so is the tendency to breathe (or why would you be struggling?)... So ignore your lungs. Lungs don't have anything to do with breathing in hyperspace. Instead, continue on with flowing with your tendancy to breathe (I'll prana your chi if you chi my prana), and keep moving through the tunnel with that same one-pointed will...
Once you reach the mouth of that tunnel (or tunnel analogue, whatever it may be that trip), breathing won't be an issue any more, and everything will just fall into place and make beautiful sense in the perfect way that only your brain can
.
Myself and a few others I have known with this challenge took a few trips to get the technique down. It's a bit odd and challenging, but after a try or three, it's like riding a bike (into hyperspace). Also, using the same technique on the way down can ease the re-entry process, and leave you in a state of incredible access concentration/rapture that aids in contemplation and integration like nothing else I know.
Good Luck, and Godspeed!
