Reality is “real existence, what is real, the aggregate of all that is real”.
Perception is “understanding”. What you understand of reality is not the aggregate of all that is real.
This is how multiple people can observe the same reality and yet arrive at totally different perceptions of reality. People create what it is they desire to perceive. It is common that our desire and that of reality may not always be in congruence.
Remember, your perception of reality is not the entire reality.
Not everyone perceives as you do.
