VR in its current state prohibits a feeling of self. This is why people don't fear dying in video games.
If/when we find ourselves in a much more robust VR experience (touch, taste, smell, etc) the fear of dying will return. Because we are convinced of the self inside the environment.
Is the origin of our experience our brain? If something seems real to us through our senses processed through the brain should we be able to accept it as reality? Would we be able to accept that the astral projection experience was just as real as our standard reality? That would mean that religion was a reality for some people but not others. I dont really think that we can bring things into being by just thinking about them. Or can we? Hmmmm
Consciousness is what you know combined with what you're about to know. Subconsciousness is a primordial facet of consciousness where thoughts are pulled apart and put back together haphazardly which literally creates something new. Usually it results in a nightmare.
If I had to guess I'd say most of our abstract thought processes have come from the subconscious. It can sometimes be right but it's usually wrong. I would question the merits of any subconscious thought.
