The visions I have on ayahuasca (to answer Snare and rackets question) were entirely new to me. I've never had drugs before ayahuasca (unless you count a few puffs of someone's joint one time).
the journey on average lasts 5 hours, unless the facilitator puts extra dmt in, then I'm on a longer ride. When its at its strongest I sometimes lose awareness with the outside world. But not every time. Often I lose connection with my body, I cant work out where my hands are for example, if I move them getting a fright that they're still attached. I can feel like Im completely bodiless. Up seems Down, and down seems up. The worst thing you can do is lie down. if I sit up and concentrate on my breath then it's not so overwhelming. music really helps me to stay present. My visions are usually colourful bright fractals, like sacred geometry. I don't usually have distinct images, but others often do.
In one journey the plant spirit was teaching me not to put trust in my egoic mind, she did it this way... Every time I had a lucid thought I heard a huge clash of symbols beside my ears.... Like a 'wrong thing to do, try again' message. this has helped me hugely since to isolate the lies (unwanted beliefs handed down to me by parents, religion, society) my mind tells me and instead listen to the truth in my heart -which is 'all is love, there is nothing to fear'. My quality of inner life has increased exponentially since.
Another time my intention was to express unconditional love in every circumstance of my life. I remember sitting up with my arms raised and energy that I would describe as unconditional love pouring into my body, my body was shaking and my mouth gaping wide open in astonishment. The next day I sent an email to 2 people who had kicked me off my land, abused me, turned people against me, and vandalised my house. It had the song link to 'Im sorry, please forgive me, thank you, I love you'. My forgiveness was so complete I felt there was nothing to forgive and I thanked them. This produced such a feeling of lightness, like the weight of anger/hatred had been removed off my shoulders. (My first ever ayahuasca journey gave me the gift of complete forgiveness to the JW cult and a grateful attitude for my experiences within that cult). There is no one in the world I hold the slightest inkling of a grudge against... Thanks to ayahuasca.
another time when the 'I'm sorry' song was being played in ceremony and the shaman was calling out asking for forgiveness for any life where he did wrong to another person, I did a huge vomit and while vomiting had visions of myself raping, torturing, murdering people. this helped me understand even more how everyone of us is connected as a whole throughout history, and that I am just as responsible for the injustices being committed... So don't get self righteous just because in this lifetime I've been a kind person. And understand the ultimate innocence of the inner essence of each human, only fear can produce actions incongruent with the original innocence.
i've been reading Jung's autobiography, and the visions he had which he studiously documented over his lifetime he described as coming from a collective consciousness, and I concur with his findings. The visions on Ayahuasca are of a similar nature regardless of who takes it. Just google ayahuasca and look under images. once you've taken it these images are extremely familiar. Yet google alchemy images and there is a similarity, google Jung drawings (his mandalas to describe his central beingness for each day) and again a similarity. How can these be similar, yet not part of mainstream art?
i cannot believe humans are simply a concoction of biology and chemistry. Qantam Physics is the new science. Newtons laws and the like are old fashioned. Even the new studies showing that our DNA changes as we change our actions and beliefs, this is fast obsoleting beliefs that DNA is fixed. Try reading Gregg Braddon and Bruce Lipton.
And listen to Terrence McKenna on YouTube, he describes tripping very well, and studied physcadelics scientifically and experentially. His son Dennis McKenna also studies the same.
