This is something I could write about for an hour or two. I went through a phase of my life where I utilized various medicinal plants nearly all throughout the day, 6 days a week for nearly 3 years. I went through various rests with this, but my purpose was to stretch the confines of the mind. I discovered various things about the plants and also reality in doing this, what they actually are there for and what they actually do. Many of these experiences were felt and witnessed by others, the vast majority of them are subjective.
I have a theory on how a good majority of this works as my work with the plants stretched out over a long period of time. The first thing to note is that the plants increase your connection with the spiritual universe and make the two universes (spiritual and physical) overlap. The higher the concentration of something like DMT is in your system, the more your brain will have the ability to more directly interact with the physical universe and the better control you have over your mind, the higher level of direct manipulation with the general universe around you is possible. After a while of utilizing the various substances, they no longer make you hallucinate in the sense that you will not see anything that is not actually there that cannot be seen by others. This is again subjective and related to my own personal experience. These experiences can be magnified and done purposefully by group intention and agreement, particularly with unification.
On to the stories. I have experienced micro teleportation (teleportation of objects witnessed by others) macro teleportation (teleportation of large physical objects, myself, my car with myself in it, and other human beings who were moved from one location to another.) For example, there was once a man travelling with us, and he vanished and we needed to leave the area we were in (meaning he had gone somewhere else). Two of us who were taking the medicine looked into a spot and materialized this person who was not taking plant medicine, moving him from one location to another.
I have also experienced bi-location. For example I was in one area singing outside taking plant medicine. While I was in this area my brother witnessed myself driving up in my car in another area, 15 minutes away. He saw me pull the car into his shop, park, and then turn the car off, turn it back on and drive away. I was maybe 7-8 blocks away outside of a temple singing.
I have also experienced very rapid regeneration of the biology. One time about 3 years ago, there was an attempt on my life in Puerto Rico where I had someone who was posing as a friend drug some of my food, trying to take my life. The drugs formed a reaction in my body that made me claw off a good majority of the skin on my face. Normally if my skin gets cut, it takes a normal amount of time to heal. 7 days, a couple of weeks maybe depending on where it is and what happens. In this case all of my skin supernaturally regenerated back in 72 hours somehow, and I can only attribute this to the plants. This scared the hell out of the person who had attempted to take my life as several days later he (in fear) called a bunch of people over, trying to organize setting me up in some manner to discredit me.
He pointed out: "Look at his skin!" To which the police replied: "His skin is perfectly fine." In 48-72 hours my skin regenerated brand new with no scarring, like the event had never happened. I have also experienced other bizarre phenomenon such as this (related to healing at supernatural speeds, massive strength increases, etc).
Again, I have a theory as to how all of this works and I believe a lot of this stuff could be documented by someone with experience. However some of the phenomenon are more tricky and I do not understand why they happen or when, as it seems to be random. Examples of this would be teleportation. I have no idea how it works or why it happens sometimes and not at other times.
It is simply something I have experienced many times on plant medicine in one form or another.
Other phenomenon I have experienced such as keeping a phone charged on 1% battery and charging it with no cable as I'm walking doing a podcast from 1% - 50%. I did this by imagining I had a charger cable that was plugged into my computer at home, stretching through a doorway in the universe and also plugged into my phone. Apparently my phone did not know the difference between actually having a cable and me simply imagining the cable was there. I am curious to if I could do this without plant medicine after perhaps an hour of meditation as it seems simple to do certain kind of small level miracles, and I have become convinced that the universe is very easily manipulable by the mind with right concentration and enough spiritual energy which has been generated.
Anyways, I hope that these stories help you understand some of the things that are possible by utilizing plant medicines. I don't think they are encompassing or nearly all of the things that can be created. I have friends for example that utilize magic mushrooms to do martial arts training and it massively increases their bodies capacity to break through physical barriers of biological resistance, resulting in being able to move at what appears to be supernatural speeds and things of the nature.
Oh, one more thing I have experienced is time reversals. It being one time, and moving backwards in time. I have not attempted to utilize that same kind of phenomenon to move into the future. We did this in a group environment by multiple people utilizing plant medicine, and agreeing on an outcome and an intention, commanding it to happen. We once experienced moving backwards in time a full 90 minutes. To be fair, I am not the only person I know who has experienced time reversals. I also know other people who are enlightened who have experienced these phenomenon without medicinal plants. The plants, however are a powerful tool for spiritual advancement and should be used wisely.
