Physical reality is defined in Metaphysics as an image being projected and then perceived by the non-physical Mind...
Physical reality, from a metaphysical viewpoint, is often referred to as "not real" or "an illusion".
While it is true that the physical Universe we perceive with our five senses is in fact nothing more than an image in our mind, it is nonetheless very "real".
The experience of it is "real", because the one having this experience is also "real".
The word "reality" is defined as that which is known to exist.
To test this definition, ask yourself who is having the experience of reading this page at this moment? The answer is, you are. If you did not exist, you could not be here reading these words. Therefore, you are real simply because you are aware of, or know yourself to exist. (See "Epistemology" for more about the nature of knowledge versus belief.)
The physical Universe is real because you know it to exist. It doesn't matter that it is an image in your mind, or holographic in nature. These qualities will have an impact on how you relate to the world and other people in it, but it does not disqualify the reality of your existence and experience.
Some - maybe most - become depressed when they are "disillusioned" as to the true nature of the world we find ourselves living in.
If the physical world isn't physical, if your body is just an image in your mind, then many may wonder "what's the point"?
The point is that you are here. You are having this experience. You are discovering what you are not and, by contrast, what you really are. All of this contributes to the eternal "knowing" of the consciousness that is the life in all.
Just as "virtual reality" allows a human being to safely explore otherwise impossible scenarios, physical reality allows the soul to experience that which is otherwise impossible.
Being "separate" is not possible in the non-physical realms. That is why the human mind created this illusion - to safely have an experience that simply would not be possible any other way.
Just because it is an "illusion" of the mind does not make it any less real!
The Spherical Wave Structure of Matter:
Despite several thousand years of failure to correctly understand physical reality (hence the current postmodern view that this is impossible) it is actually very simple to work out how matter exists and moves about in Space. The rules of Science (Occam's Razor / Simplicity) and Metaphysics (Dynamic Unity of Reality) require that reality be described from only one substance existing...
Physical Reality: Physics, Quantum Theory, Metaphysics...
Learn about the physics of the large. Learn about the physics of the very small. Learn about other way cool phenomena and why they are the way they are. Expand your sphere of knowledge...don't live in a bubble universe...
~~ Perception: A Function of the Body Being Projected by the Mind: The human mind, which exists outside of time and space, is responsible for both the projection of the human body and its five physical sensors. Perception of the physical world is thus created in the mind.
