Tunnel of Foreshadowing

Go To

A device by which the audience or a major character (or both) gets a brief view of other major characters who have yet to appear in the story: an optical effect gives the sense of a moving tube or tunnel, down which translucent or opaque images of various characters swirl and recede. When not found as part of the opening credits, the Tunnel is usually the result of some mind-altering experience, such as the process of being Trapped in Another World.
