The Big Dictionary of Dreams

by Martha Clarke
Climbing a slope is a sign of the effort that the dreamer in real life is doing or should do in order to achieve a desired goal. Thanks to the context of the dream and the interpretation of the other oneiric symbols of the scene, it is possible to understand the message the unconscious is trying to convey.

A slope may indicate the direction one’s business or personal life is headed. An obtuse decline indicates a slow descent and a sharp incline suggests the dreamer needs to pay more attention to his or her responsibilities and also to the duties that others are obligated to perform on his or her behalf.
