What is reality? Mainstream science describes reality as “the state of things as they actually exist”. One simple interpretation of this very broad definition is this: reality is everything we observe to be real.
But hang on – I consciously observe the lucid dream world, so does that make it a genuine reality?
Just how many realities are there – yours, mine, his, hers? As Einstein suggested, is every form of reality merely an illusion? Is nothing real?
The human brain is split into two distinct halves: the right brain and the left brain. They have completely separate roles and agendas. Some would even say they have separate personalities. However, in order to function, the two halves of the human brain must communicate as one via the corpus callosum.
The right brain is all about the present moment; right here, right now. It thinks entirely in pictures and learns through the kinesthetic movement of your body. It absorbs energy from the world around you and translates that into information for your sensory systems. It does not know the difference between your individual consciousness and the world around you. The right brain only sees one universal energy field of awareness.
The left brain is a very different place. It thinks linearly and methodically. It picks out countless details from the events in the past and makes calculated predictions about the future. The left hemisphere thinks in language, which creates your internal voice. Crucially, it makes you aware of your existence, as a separate being from the mass energy field perceived by the right brain.
Imagine if the human brain had evolved with only the functions of the right hemisphere. Your perception of reality would be completely different. You would be drifting around in a universe filled with energy in the here and now, with no perception of the past and future. You would not know where your body ended and the ground began, or the difference between you and me.
This is a very different perception of the world. But would it be a more accurate representation of reality? Knowing this about the human brain, the question “what is reality?” changes form. It now hinges on your individual perception. This has led to multiple theories of reality by various philosophers and scientists.
Phenomenological reality is based on subjective experience. Whatever you observe is instantly real to you. This theory of reality means that unreality is non-existent. Therefore lucid dreams, hallucinations, spiritual experiences, and astral travel are all forms of one subjective reality.
Consensus reality is based on the opinions and observations made by a group of people. A few individuals may decide on an interpretation of an event, which spreads across entire societies and becomes a consensual truth. Religion is a good example of a socially constructed reality.
Non-reality simply means that there is no such thing as objective reality. Every possible observation or interpretation is tainted by subjectivity and therefore does not constitute truth. Nothing is real! This is supported by quantum theory, which states that prior to observation, nothing can be said about a physical system (read In Search of Schrodinger’s Cat by John Gribbin for an excellent introduction to this topic). This theory is further backed by the Double Slit Experiment, which suggests our mere observation changes the outcome.
I think philosophers will be stuck on this one for a while. Our understanding of the universe is very much limited to our own capacity for understanding… The truth is out there – and it is probably much crazier than we can imagine.
