Yes, its called lucid dreaming, and 99.99% of everyone doesn't seem to think its a big deal that we interdimensionally travel every time we go to sleep, for some reason. Its almost as if society has been engineered to specifically downplay that fact. Here you are parroting exactly that propoganda without even giving a second thought as to why you believed it in the first place. When has the system not lied to you?
Why would it not lie about some of the most fundamental reality shattering aspects of our existence, when it expects you to get "learn" in school for 12-20 years, and then work your 9-5 as a specific cog in the social machine until retirement and death. Why do you think that is a rational thing? Rationalism is only a few hundred years old, but for many thousands of years, our ancestors, in civilizations all around the world, believed in the supernatural, spirits, gods, etc.
As you correctly state, a lot of it is bullshit. We don't know which parts of the story are real or fake, which parts are just made up, which parts people believed due to experience, but wrote down incorrectly, which parts are misunderstood because we didn't have a scientific mindset.
Now we have a notion of physics and forces of nature, and yet, we also have lucid dreams, meditation, astral projection, remote viewing, all things that exist within the possibility of human perception, but we don't have an adequate scientific understanding of. Its not as if these things are impossible to study, we just have rationalist atheist skeptics as the mainstream scientific culture, so these things will always exist on the fringe in the shadows.
Some people however, do consider these things, and experiment with them. That is the basis of occultism. We aren't occultists because we know the answers, how to do 'magic', we are occultists because we want to find the answers, and to ask the question, "how far can consciousness and awareness go, when unleashed"
