Orb shadow

An orb shadow is a hallucination or vision that people experience after using the Orbs of the Prophets. In Bajoran tradition, orb shadows occur if a person ignores what the Prophets told them during their orb experience.

In 2372, Benjamin Sisko had several orb shadows in which Opaka Sulan told him he was the true Emissary of the Prophets after he stood down in favor of Akorem Laan. 

In 2376, after the destruction of Sidau, Sisko began experiencing visions like orb shadows, although they related to the future.
