Dreaming and thoughts and death

I was recently solving some chess puzzles online, and something weird happened. I was really sleepy as it was late but I was determined to solve however as I could so I kept on trying to. And at some point I forgot about the puzzle in front of me, and I started instead making up my own thing. I started drawing on the chessboard using arrows, and I started taking pieces wherever I wanted without any regard to the laws of chess.

There I discovered something. When your brain activity gets low (I was really sleepy, at around 4am, as it was very well past my bedtime, although more experimentation needs to be done, perhaps with psychedelics since we know that they indeed lower brain activity), the rules that you once held start disappearing, and your reality becomes whatever you make it to be. And if there is a subtle thought in the subconscious that holds on to some sort of a version of reality (hence why I started drawing on the chessboard using its own arrows), then the disappearance of most of those laws combined with what little exists adds up to all these seemingly illogical things we see. But we know for a fact that they are not illogical since we can then imagine a scenario where it could be true, like non-Euclidean geometry.

So combine this effect with a lack of sensory input, and boom, dreams. And I believe there is no way to actually achieve this state and still be connected to this reality. Since once you lose all logic and become unquantifiable, there is no logic I can think about that would then connect you to this reality again. As I discussed in a previous post about how it doesn't make sense to truly put a boundary on something that inherently lacks boundaries, it is hence why I cannot (perhaps yet) see the logic in how we can "come back" after we achieve this. Perhaps we achieve this when we die...

But from a physicalist perspective, and this is as valid, we could say that as those laws of nature disappear from the mind, what remains is what gives the idea of different realities, as then those combined lack of logic and the logic that remains make up things, but it suggests that we cannot truly imagine things beyond some for of logic that we can grasp. Even the things I talked about in the "non-logic" blog post, though they may be beyond grasp, we can imagine. But "grasping" is BASED on this reality. which then begs the question (from a physicalist perspective) of where to draw the line between the quantifiable and the not.

So, Do we draw the line between the mind and separate reality, or do we draw it in between reality and something else but something that's explorable through the mind? But if it's from a physicalist point of view, we would have to explore it using the laws of reality since we are bound to it.

We must first think and do the unthinkable or the undoable to prove this physicalistic perspective wrong, but then the question becomes, since you thought it or did it, do rules of reality allow you to do it?
