Interpretation 1 — Theresa Cheung
Unable or unwilling to speak, a silent witness in your dreams represents an area in your life in which you are not expressing yourself. According to Jung, favoring the intellect over your emotions or vice versa can make you speechless and unable to communicate fully and openly with other people. The only way to create intimacy in your life is to find a better balance. In dreams, twins or mirror images of a figure often represent two aspects of your personality.
If they are not identical, they suggest conflict between your inner and your outer realities.
If they are identical, they are a sign of inner harmony.
