Evening signifies old age, wisdom and many years of Spiritual experience. The evening can be a synonym for twilight and the boundaries of our conscious mind. At this time there may be 'apparitions' around, of which we do not become aware until we start working with the unconscious. When we are aware of it being evening in a dream, we need to recognize the fact that we need time for ourselves - perhaps relaxation and quiet peace.
