Dreamers Dictionary

Vision: Seeing a blank signpost on a house or door: you are facing a confusing situation—try to find a solution or alternate route. Somebody handing you a signpost means pay attention—someone is attacking you and you need to respond quickly. Seeing a sign above a door of a shop: friends are envious of your success and you are right to be annoyed.

Depth Psychology: A sign with instructions on it is a challenge to express more of your personality.

Pay attention to any sign or signpost in a dream.

If you miss or forget what it says, ask your unconscious to give you the dream again; and prepare yourself, before going to sleep, to concentrate on the sign this time.
