I am with Alexander on keeping a dream journal. It was a primary practice including daily meditation that got me to the place of experiencing lucid dreaming and the OOBE every night, so good to know that you, zenbooster, have been keeping a dream journal.
I once read a technique suggested by a group of "dream hackers". It's called dream mapping. The bottom line is that when remembering and writing down dreams, focus on where the plot unfolded. For each dream, if possible, it was proposed to draw a map, a plan of the area where it happened. When a lot of material accumulated, it was proposed to compile one common map from disparate maps. The hackers claimed that this should lead to insight, an avalanche-like recollection of many forgotten dreams. Apparently, I do not have enough material, although some forgotten dreams were recalled against the background of mapping, and this activity in itself is simply interesting. Now I keep a diary in the Obsidian program (
https://obsidian.md/), and instead of dream-mapping in its original form, I supply dreams with tags. Tags refer to places, people, certain objects, and so on. This is at least convenient. Although the map of connections between dreams and tags is overloaded, you can use the search by tags.
Wikipedia says it may have some toxicity to the kidneys but it's unregulated overall
I also read about nephrotoxicity. At least after using it, I did not notice any negative effects.
I have never heard or calea zacatechichi before. With a 5 decade interest in ethnobotony I am always happy to learn of a new to me herb.
Regarding what they write on Wikipedia, I can say that I have never experienced nausea or vomiting from this plant. The tea is bitter, much like coffee without sugar. Compared to the most bitter thing I have ever tried, a tablet of levomycetin (chloramphenicol), the drink turns out to be quite tolerable. If you drink a very strong tea, or smoke a hookah, either luminous dots appear before your open eyes, as in the dark, or some kind of small static waviness, some subtle change in the image that is difficult to describe. At one time I grew a plant on a windowsill, in the middle zone of the European part of Russia, and regarding an allergic reaction, I can say that it could occur if the crown of the plant was disturbed. There has never been an allergy to dried leaves. At the same time, it never bloomed for me, but it worked like a oneirogen.
The sesquiterpenes known as caleicines and caleochromenes may be active in its effects on sleep.
I wonder what kind of compound affects dreams ... Someone on the network suggested that one of the substances that make up the plant must be a cholinomimetic, and by the end of the weekly course, dreams become brighter against the background of increased levels of acetylcholine in the brain, but Apparently the mechanism is more complicated. Today I again felt the characteristic "mood of zakatechichi" from a dream, although I did not remember the dream itself, just miserable fragments. This mood is a certain feeling of gloom, inevitability, even irreparability of what is happening. This did not happen from cholinomimetics ... There is also information that dry extracts that are on sale do not work as a oneirogen. I don’t know what solvent was used there, but apparently the key compound does not dissolve in all solvents.
P.S.:
They also wrote that it
should not be mixed with citrus fruits. I do not know why...
