Spiritual Meaning:
Twins illustrate the idea that two spiritual concepts or ideas, while separate at the moment, can achieve unity. A spiritual conceptualization is that while Unity is the Original State and splits into Duality, Duality must eventually reunite into Unity.

Psychological / Emotional Perspective:
Often in everyday life we come up against conflicts between two opposites. Twins in dreams can actually represent two sides of our personality acting in harmony.

Everyday Material Aspects:
In dreams twins may, if known to us, simply be dream characters. If they are not known to us then they may represent two sides of one idea.
