The Laws of Subjective Reality
You can never experience something directly.
The beauty of subjective reality is that every experience is yours and yours alone. You can never experience something outside of yourself. When you have a conversation with someone, you may think that you both are experiencing the same thing, or something similar, but the only way we can assume that is by thinking it. If we were in a dream and assigned intentions to all of the different characters, then wouldn't it be just a mind game we play with ourselves? Of course dream characters do not think for themselves, right? Well, the same rule applies to real life. Our intentions we assign to others are simply mind games we play in order to make the other person real to us. It would be pointless to see them as a puppet, even though that might be the truth and probably is. We can only experience the effects that are given to us to experience. This has been described much more elegantly by some philosophers, so this is not new.
Just because similar realities are reported to us, we all live in our own personal reality.
Having two people look at the color red and report that it is red does not mean we live in a an actual objective shared reality. This is a common mistake someone could make when assuming reality is objective. Objective reality is not provable. It does not exist. Everything you experience is subjective and personal. Again, we can look at the rules of a dream here. If you had a dream and saw something red, another character in the dream could call it red too. What does this prove? Nothing. It just shows that we are experiencing a certain thing that has shared reality as one of its features, not one of its fundamentals. Shared reality is not a fundamental thing. Every reality is personal. We can look at the inner life of a person who deals with hallucinations, or someone that is on LSD permanently to understand that reality is subjective. If everyone had hallucinations, then it would be called normal and then everyone who didn't would be paranormal.
Death is an experience/ Not a destination
We see a body die and we think the consciousness perishes with it. This cannot be true in a subjective reality. Since objective reality does not exist, brains do not exist either, since they are something we observe and are not part of our inner experience. Only our consciousness is part of our experience. It is the totality of it, the final frontier. If anything, the brain is simply a good representation of what experience we ought to be having here. It is a constraint, a symbol. Again, think about a dream. If you can acquire lucidity in a dream state, and cut open your head and there is a brain there, what does that prove? (See previous paragraph to make the connection.) Of course an assumption could be made that we are sleeping and a dream is just a bunch of patterns and data that we are sorting out. That is the same thing that is going on here by the way
You can never see your consciousness
Consciousness is non physical and therefore cannot be observed. We can observe many different effects of it, like this physical world, and the physical brain (hallucinations), but we can never see it. It is invisible. It will forever be free from the microscope of objective thinking. The only thing that physical science can do is observe effects. It cannot explain consciousness from something that consciousness creates. It's like trying to make digital players in a computer game prove that their system created the player that is controlling them outside the television. This basic truth has been known for a long time. Buddha, Einstein, Bohr all knew our reality was an illusion.
