1) Serotonin is called a neurotransmitter because it telepathically transmits information from person to person. It's not just a mood stabilizer but a tool in our communication, just as much as mirror neurons are communication tools that allow us to interact with body language.
Serotonin sends messages through quantum entanglement like little envelopes in the form of "energy" or "vibes," and so much more. It allows for nonverbal communication and it's why we can also feel the moods and intentions of not just animals, but plants, if we pay attention.
2) Human beings, other animals, and plants all contain serotonin. Our own individual sources become difficult to reproduce because of different reasons including trauma, generational patterns that might stem from generational psychological wounds that get passed down in the DNA, lack of proper diet, and others.
3) Trees can become sick, and so can human beings. Trees and humans need healthy communication with each other and with their own kind, and without it they become ill and stop producing enough serotonin, which causes them to have more trouble communicating, thus a vicious cycle happens until it's broken.
4) Serotonin helps regulate the nervous system. I know this from personal experience because now that I have higher levels of serotonin my brain has been going through washing machine cycles of automatic meditations. My thoughts no longer loop in ruminations, imaginary arguments or fights with people, or other negative daydreams. I no longer use escapism as a drug either. My thoughts flow from one to the next and process out in a way that's helpful and effortless like the channels in my mind have been unclogged.
5) Serotonin, like melatonin, helps produce rapid eye movements, except serotonin helps us do this while we're awake so we can process our emotions and move on with our days. Our daytime wakefulness is the wakeful dream with the conscious mind, while the nighttime sleepfulness is the sleepful dream with the subconscious mind. Serotonin is our sunlight and melatonin is our moonlight.
