Mind and brain correlation

The mystery of consciousness is the biggest one today in my opinion, and when (or if) we discover how it works, we will get a whole new look on existence and maybe create artificial intelligence.

Most people will agree that there is a correlation between your brain and your mind, as can be easily demonstrated with tons of examples. However, I can't understand how some people think that consciousness is a mere product of the brain, that disappears when we die, it just doesn't make sense to me. We aren't just machines, we have a subjective consciousness, how can subjectivity suddenly emerge if objects are set in special patterns? (Atoms forming as a brain)

Now, you can still say the same thing even if the consciousness is eternal and separate, why do we have a consciousness and not a rock? Some people will say that rocks have consciousness too, because everything in the universe has, but what is it that separates us then? Some people will argue that we are all One, as Eastern religions say, but if that's true, it can be explained if the one consciousness will be reborn as everyone one by one, so we are future and past lives of each other.

Because you can't argue against the fact that we are separate consciousness right now, we are different subjectivities so to say. Unless I am the only one really alive and everyone else are just illusions that seem to be alive like me, but I really doubt that.

So how are mind and brain connected? Can electricity be a part of the puzzle? Our thoughts are said to be electrons moving, just like electricity, right? Ghosts are often reported switching on lights and televisions on and off, which also work with electricity, maybe there's a correlation there...

I do believe in reincarnation rather we ceasing to exist when we die, but I don't think our memories remain with us to our next lives like some people do. To make an analogy, let's say our senses is like a window on a wall, and our memories are like pictures on the wall, emotions, motivations, thoughts and reasonings can be thought of as entities whispering to us (this is like I said only an analogy of course, a theory of how the brain works), and when our body dies, the wall disappears, and we "turn around" (our consciousness continues it's journey). I don't know if you people think the analogy is stupid, or maybe someone else has thought the same thing? Because there is an almost indisputable connection between the brain and mind in some way.

Even if some people would disagree, I read in another thread here a theory that there is really no connection at all, and that everything that happens to our bodies and brains affect us like placebo effects. It really is an interesting theory, I've never thought of that before...

Now, what about the astral plane, just a mental phenomenon, or maybe there actually is an astral plane? Hell, maybe even deeper planes than that that we also function on, I've read some Theosophy stuff, which claims there are not just one or two dimensions that we exist in simultaneously, but seven!! It got really confusing, reading about it. It said alot about how one plane affects the one beneath, but it was a bit confusing as well, fancy stuff.

And what about quantum mechanics? Do we perhaps have free will after all, we can't recognize the patterns in subatomic particles... Or maybe it really IS random? Maybe there is no predetermination or free will, only random will.

This grew into a very long post apparently, but if someone has opinions, please let me hear them, let's try to find a possible solution to this mystery. :detective:
