While encountering various experiences, the mind assigns different amounts of reality to them. The mind calls, some experiences as more real and some as less real. It has no way of telling if something is less real, unless it encounters an experience, which it thinks is more real than the current one. Reality is relative to where we stand, depending on our ignorance or knowledge. We keep arranging experiences on a scale of varying reality, till finally, we find that all of it is relative. There is no absolute place to stand. There is no absolute reality.
