The Dream Book of Self-Knowledge
- if signs appear often in dreams it indicates the dreamer's indecision.
- informational signs: used to make minor adjustments in the life journey; the sign's content should be perceived since the unconscious is providing us directly with advice and recommendations.
- sign on a door: can tell us more about the nature of the level beyond the door; see Door.
- prohibitory, instructional, warning: emphatic reminder to observe basic rules (usually moral).
