Mind-body. That you can think yourself sick, or well. Not like magic, but a lot of the time. Like how people won't get sick until vacation a lot of the time, they say "don't have time to get sick" so then on the day off, the mind tells the body "ok now you have time!". All of my kids were born on a day off or weekend, same thing in a way. And once I read a book where the protagonist' hands were burned, very vividly described, and got blisters on my fingertips.

I just really believe a lot of physical illness, and health, comes from thinking.

Uff, i have a lot:

Life on earth is a huge organized organism. It created intelligent humans deliberately sothat we can spread life to other planets. Living beings (plants, insects, other animals, fungi) could not do that otherwise.

All life is sentient. Sentience doesn't come from the brain, rather it comes from the hormones in your bloodstream. When we sweat, these hormones enter the air (apparently within the fraction of a second) and other people can smell them. That is how we can instinctually know how others are feeling.

Also i have a lot of mythology:

Heaven (realm of all ideas, knowledge and forms) and Earth (origin of mass and material) are a love pair. Because they couldn't easily meet (there was an insurmountable gap between them), they created a bridge, which is life. This way, heaven supplies the shape (genes), and Earth supplies the body, and these two can be together in this way.

Viruses are books. They have a cover (shell) and contain scripture (RNA/DNA). We humans let them in because they are nature's messengers and have a specific purpose, which is to exchange some information.

That's a long list I've only skimmed it and I didn't find the theory I like most, the stoned ape theory. That belief that some distant ancestors ate some shrooms and discovered art and a higher state of mind. I've taken a microdose a little too high and my vision was like an impressionist painting for a few moments and it made me so happy because Monet and Van Gogh now made absolute sense.

It might be a little too convenient but I think it works and it's really sweet.

Feng Shui, though I mostly credit it to the Dear Modern channel breaking the concept of qi and energy down into stuff like human traffic flow, activities, scenery, and noise, and using that to optimize spaces for comfort. It's mostly psychology, and some of the superstitious stuff I'm not really into.

I believe that literally every esotheric and nonesotheric bullshit is more trustworthy than everything a politician says at any given moment.

Definitely the lunar effect, but that is still under study. There's a documentary called "The Shark Side of the Moon" which follows a scientist trying to prove a lunar effect on sharks. There's also some inconclusive evidence of a lunar effect on people with bipolar disorder; the full moon might trigger mania, probably due to excess light during nighttime. Context: >!People with bipolar disorder (known as 'manic depression' years ago) are very sensitive to light, substances, and many other things that can trigger manic or depressive episodes for them. The possible mania under the full moon may be a reason behind myths like werewolves and terms like 'lunatic'.!<

I'll edit if I find more.

Edit: I found another one which I would easily try or suggest to others if evidence-based therapies have failed.

Eye movement desensitization and reprocessing (EMDR) is a form of psychotherapy in which the person being treated is asked to recall distressing images; the therapist then directs the person in one type of bilateral sensory input, such as side-to-side eye movements or hand tapping. It is included in several guidelines for the treatment of post-traumatic stress disorder (PTSD). Some clinical psychologists have argued that the eye movements do not add anything above imagery exposure and characterize its promotion and use as pseudoscience.

Body Memory

I mean, cellular memory and muscle memory exist.

It's hard resisting the power of the moon.

I really want to believe the Assassin's Creed concept that our DNA holds memories from our ancestors.

That wiki article is very biased.

It also has problems distinguishing pseudo medicine (proven not to work) from alternative medicine (not conclusively proved or disproved).

Not sure either of these counts fully as what OP is looking for, but -

The idea of the technological singularity feels right to me. There's a whole section on the wikipedia page about scientific objections to it, and I get that, but if we don't kill ourselves before then, it seems like an event that almost has to occur at some point, to me. And maybe it zigs instead of zags and we get star trek. Or maybe it zags and we get terminator. But probably neither of those I'm guessing, and these days it's hard to imagine that it would put humanity on a worse trajectory than we seem to be on today.

Similarly, but less seriously (for me) I like to consider the whole "maybe we're in a simulation" theory.

Maybe like a limited Gaia hypothesis. The whole planet is a conscious thing, we are its braincells and its hands.

I think that currently society is too polar about this issue. A lot of so-called pseudoscience have a lot of anecdotal evidence that should be taken into consideration and don't have a lot of science to deny them. On the other hand a lot of them do have that so there is an issue where there's a lot of people who believe a lot of different pseudosciences because some of them genuinely seem to have results but the people who go explicitly by scientific research sometimes can group all of these together. For example, homeopathy is obviously bullshit, and there is a ton of scientific research that shows that. But, for example, a lot of Chinese medicine, which has no scientific backing, does seem to have a lot of anecdotal and historical evidence that suggests that if science does look into it, they might find some actual results.

I don't know what lunar effect is, but the description you gave sounds very plausible. Like, why wouldn't a full moon affect the behavior of humans and other animals? How it affects them? To what degree? Sure, that's debatable. But generally affecting them, that sounds reasonable. It's a significant change in the night. It lights up the night more and It wouldn't be a stretch to assume that some animals might use it as time management indicators that might relate to biological cycles.
