Theories about the nature of the world. Metaphysics or whatever. Do they make sense?

It's honestly what's better for me to do at the moment, and that is because of more than one reason. It will help me to focus and challenge the ideas in my mind, allow me to actually think about what's going on... and well, it's more entertaining and useful than laying on my bed or doing whatever else I can do. It will also have good results, a new worldview.

So... let's begin!

Theory list
I don't know what reason do I have not to believe in the accounts I have seen, but what do they tell us? Are they real?
 * Psychic powers.
 * The world is a simulation?
 * How do the phenomena of the world work? What's unknown to us? Does reincarnation exist?
 * Etc.

Other theories which I need to think about. Unless I get stressed...

I remember this time when I acted like an idiot who made these people feel bad.

Mainstream metaphysics, cosmology, physics beliefs.
Actually, I'm not sure if I'm using these terms correctly. Maybe I should research more about them. But before doing so, I think that a good idea would be to try describing what I wrote in the heading of this section.

> Earth is a planet.
