A phenomenon cannot be a reality simply because it serves a purpose or purposes. Take a dream for example. The dream creations are purposeful; they serve the dream-purpose. The dream water quenches dream thirst. The dream creation is contradicted in the waking state. The waking creation is contradicted in the other two states. What is not continuous cannot be real. If real, the thing must be ever real – and not real for a short time and unreal at other times.
