The mind is capable of producing memories and this is proven and looking back on events in my past it is sometimes hard to distinguish if some events really happened or not.
That's not really true. You are remembering an event, and if at that time you knew if it was really happening, then you will remember that too. Your memory might get fuzzy, but you remember that it happened. You might doubt your experience years later, but that's not because of faulty memory. If you are going to say something is "proven" give a citation.
We really need to see that something is going on here to normal ordinary people, and it has been going on for a long time. If we keep wanting to sweep it under the rug because of lack of understanding, and saying it's all in people's heads, we will never get any insight into what is really happening.
As science started moving people away from any kind of spiritual belief, we became very materialistic. If you can't measure it, it's not real. But actually it's the lack of understanding of the phenomenon. It's like arguing there's no such thing as radio waves if you don't have a radio receiver to pick them up. You can't see them. You can't detect them without the right knowledge that they exist and a means to sense them. And like so many things, that was discovered by accident for the most part. You can't measure something that you don't know exist.
So as people kept being told that such-and-such didn't exist and was a superstition, then when people experienced these things, they assumed they were mistaken and must be hallucinating. But that's only because science can't prove such things happen, but they also can't prove they don't. You can't prove a negative.
Now I'm a VERY scientific person, and always have been. But I also know that I've had many many experiences that were real, and can't be explained. Just because they can't be explained doesn't mean it didn't happen. Some involved other witnesses. We didn't hallucinate or have fabricated memories. As an example, six other people and myself witnessed a landed disk and several small humanoid creatures covered in black hair with large glowing green eyes. The creatures left foot prints in the mud and snow. We all saw the same thing. One guy even said one grabbed his arm, so he ran home... before the rest of us saw them. He gave us the same description when we caught up with him. That was about 1970. I spoke to him a few months ago, and he remembers the event exactly as I do. Then two other people saw the same creatures on two separate occasions a few years later. Did we all hallucinate this, even spread out over a couple of years for the other two witnesses? That's absurd. I bring up this story to show that there are things we don't understand going on, and they are real.
We have to accept that we don't know everything, and in fact know very little. We understand some of the
mechanics behind reality, but certainly not the reason. The Big Bang? Sure, that's a reasonable idea. But why did it happen? And what made it happen? And what was there before it happened? No one can answer those questions. If you can't answer those questions, it's like some scientist 1000 years ago studying something like an automobile. Would they figure out how it works? Would they even figure out what it was used for? Maybe, it has wheels. But why was it built and by who? I like the analogy dB uses to explain why we wouldn't be able to reverse engineer advanced technology. Send a MacBook back a few hundred years. Better yet, send an iPhone. Not only would they not understand how it worked, but they wouldn't know
what it was used for. It would probably be a sacred object from some other race of people and be considered purely symbolic. We do that to old things we find all the time.
So us trying to understand some aspects of our reality are much the same. We don't have the answers, so we reverse engineer reality based on observations. We don't understand it, because we don't know enough to even see it. Add insult to injury and we wont admit it's there when we see some aspect of it. Because our limited understanding says it doesn't exist.
So don't get hung up on what the brain does or doesn't do, because conciseness is something that's not well understood at all. That's a fact. If you have a dream about an event, and later that day it happens, what does that mean? Coincidence? Not likely. But can it be "proven" in a lab? Probably not, but that's a refection on the current state of science, and not on the phenomenon.
