So your perception of reality is a sustained state of being that’s based on your long-standing beliefs, attitudes, thoughts, and feelings. And since your beliefs become subconscious and also unconscious states of being (that is, you don’t even know why you believe certain things, or you aren’t really conscious of your beliefs until they’re tested), your perceptions—how you subjectively see things—for the most part, become your subconscious and unconscious view of your reality from the past.
