Twin sibling
A sibling who shared the womb — a parallel self whose existence asks questions about your own shape.
A twin sibling in a dream is the dream's image of a parallel self whose existence asks questions about your own shape. The twin is very close to you and is not you; the gap is narrow and is not negotiable. The dream brings the twin when something in your life — a comparison with a sibling, a counterpart at work, an alternate version of who you might have been — is now being held up close enough that the differences are sharp. A twin encountered as fully a separate person is the dream affirming the honest distinction. A twin confused with the self, with the boundary between the two going soft, is the dream noting that the closeness has begun to consume the small specific shape of who you actually are.
