How do you question reality?
Here I am going to experiment a bit and try the Byron Katie query method called "the Work" to answer the question of "what is reality" - so Is reality true? Can I be absolutely sure that it's true?
The fun part of this second question is that not many things are absolutely 100% full-proof true.
There is a simpler way in dreams though, by just watching your hands – by extending the two hands together in front of your eyes – you will then see during dream-time, that they are deformed.
You might have 4 fingers in one hand, and 6 fingers on the other, and then you become lucid.
But so far, I haven't find a similar simple trick to wake up during 'daily life' – I just know I'm not dreaming because another particular quality of 'daily life' is a possible feeling of boredom, this feeling can't happen in dream-state. In the dream things are shifting, things or events are fluids ; in physical awaken time – you can get this feeling of being stuck and being bored.
Does this mean "Reality is boring" ?
And that isn't true either, for truly awaken people – reality can be as exciting as the dreams, and that's when things are starting to manifests and both reality and dreams are starting to mix.
What is the risk of mixing the real and the illusion?
I guess there is a step forward into the interaction of the reality given as a sandbox and the potential of acting in this sandbox in a more interesting way, than being a mere consumer or a victim of reality. The step forward is to realize that we are creator, and by exercising this power we can bend realities (just like in the dream-state).
And then the question pop-up again .. what is reality?
It can't be only perceptual, because as human beings our sense spectrum is not optimized – it can't be in the mind only because for the brain reality, fiction, illusion are all the same .. informations driven experience...
What about emotions?
Reality will raise emotions, and so will books, movies, etc .. there's a whole industry taking advantages of this "feature". The emotional center is responsive to informations, everything that will provide informations is creating an emotional response. Music in particular can generate a huge emotional influx, just the vibrations of notes, can make somebody become very sad and cry or nourish an internal anger, or laugh – music has this capacity over words that are in many cases powerless when it comes to variety of languages or the audience capacity of understanding.
Music is universal, it doesn't have to go through the door of understanding – it goes directly into the emotional center.
