So for starter, i want to tell you guys about the Changa that gave this level of experiences.

a friend made an extraction that yelded almost 3g of white fluffy spice.

he was traveling and brought some aya with him, and when he passed the medicine to glass recipients, he used the leftovers in the plastic recipient and got 0.8g of freebase harmalas.

to preserve the spirit of the Caapi, he put 10g of vine, and 3 of leaf in a bottle with IPA for a week.

he also wanted to experiment with other plants, so he puts 3g of salvia divinorum, 3g of sinuichi, and 3g of calea in other bottle with IPA, also for a week.

Both IPAs had also some unmeasured amount of lavender buds.

So, friend retrieves both Ipas, puts spice and harmalas inside them, reduces a little, and adds

0.6g of salvia leaves
0.6g of sinuichi leaves
0.6g of calea leaves
0.6g of caapi leaves
and 0.6g of poejo (mint flavored plant, but sweeter)

this was dried and left under a fan for 3 days, and yelded 7.6g of changa. he added some lotus flowers afterwards.

One day before parting to boom, this was experimented, in a calm setting, with a very small, but unmeasured dose.
The experience was calm, very centered, and i noticed the the salvia was very present.

So, i did go to boom, with a friend that had also some jungle spice enhanced leaf. on 3rd day, me, my wife and my friend went to a quiet place in the healing area, and tried a good dose on a glass pipe.

I was sitting in lotus position, with eyes closed, and everything turns red. then many squares appeared, each one with a different color and vibation. so i zoomed in an orange square, and there was a guy juggling. in other green square there was a guy dressed lie a clown, doing clown stuff. in a purple square, there was someone distorting that realitty, and so on. i think i visited 8 or 9 different squares. what everyone i visited had in common, was that everyone was very happy and having a lot of fun. (Im talking about real people imy visions, not entities.)
At some point i got zoomed out, back to the red energy field, and it started to change its color, and talking to me. It said something like:
The real message of your experience is this: HiperSpace has been hacked! Everyone is inside! What are you waiting for?? Do you want to have fun in the astral? You just need to wake up! Just wake up, come on!

But at that moment, something outside distracted me, I opened my eyes, and everything faded away.

When i told my experience to my wife,she was like: Holly Sh*t, I had the exact same experience, but everybody was in the same place, trying to wake me up from the beginning, and i did wake up, i walked around, and there where people cheering me, and cleaning my toughts away, so i could stay there! (!!!)

We had stuff to do, so we did not travel further that night. but i was eager to go in again, so in the next night we went to the same place, and prepared to launch again. this time i prepared a good mind set whit meditation and breathing, and loaded the pipe with a bit of the jungle enhanced leaf, a neat white cristal in the middle, and my changa on top. a pretty good dose, since i was smoking in a pipe, and really wanted to be sure i was going in again.

The moon was right in front of us, allmost full, and very bright and yellow, making an huge reflection in the lake. I was also in lotus position but because of the moon, this time i left my eyes open.

I smoalked as much as i could, and i was catapulted to the moons reflection in water, then in the moon itself, and then my body starts vibrating, and a huge sound appears, some kind of giant flanger, that in first place i tought it came from the dance floor, but then i noticed that it was a sound impossible to be created in this dimension.
My upper body starts girating clockwise, like kundalini rotation, and that sound started to sync with my movements, all reality desintegrated in o bunch of lines (if you ever did the osho's No Dimenion meditation, it was the same effect).
At that point i couldnt figure out if my eyes were open or closed, but when that endless loop finished, reality started to form again, and i was in the same place, but diferent.
The sensation was that i opened my eyes, not the phisical ones, but my internal eye.
And when i opened my eye, i was in the Hiperspacial Enchanted Boom Land. It was the same place, but in its hiperspace version. everything was enchanted, alive, and there wasa very mistical purple aura everywhere, but most important, there were a lot of people, that werent there before i smoalked! and they where all loking at me and cheering and aplusing! He is awake! hurray! welcome!we are so happy to have you here! stand up dear one!
and i stand up, the person closest to me was beaming white golden light towards me. as soon as i could stand up, a lot of people lost interest in me and started playing again, knowing that i was ready to experiment this reality also. but some people stayed with me! talking very happy, Welcome to the wonderland of infinite possibilities! what do you want to do?
My answer was, Well is this the place where everything is possible? Sure, why not? its all inside you! and when i focused in the sacred fire, i was there, and the fire had some amazing simbols and beings that i cant describe, the dancefloor spooked me away i walked in the water, over the moontrail... did a lot of great stuff! but then i hear a voice inside me, saying, you need to go back! and i was transported to my body again, in the healing area. im not sure if i opened my phisical eyes, or just closed my inner eye, but i was back, full of tears roling down my face, and a feeling of extreme joy!

this was the most intense and remarkable experience i had in boom, and one of the best from all my hiperspace experiences. for the first time I interacted with hiperspace, instead of just being a spectator. I could move freely, like an astral traveling. i saw some entities, and small beings, but the really stuning thing was to have o lot of people interacting with me also. it seems that from some point of using a lot of dmt, te visions become less intense, but you become more aware of what happens on the other side of the veil ( maybe this name is more suitable than hiperspace because it was grounded on this reality). i start to feel that sometimes the overwelming imagery distracts you from the true learnings, and all you can do with your consciousness on DMT.

I had a couple more nice experiences in boom, but not so exciting and interesting, maybe i share them later.
