According to some eastern teachings (Tantric, Buddhist, etc) it's a good thing to ponder and meditate on dreams:
A person dreams of finding money or gold or any other luxuries. This person keeps gathering all that frenetically until waking up. When that person wakes up realizes that it was impossible to keep that wealth from the dream.
A person has a nightmare and fear all his dream. Instead of facing what causes fear decides to wake up from the dream.
A person spend all his efforts struggling to get on top of a mountain. The higher this person gets the harder it becomes. This mountain is surrounded by beautiful fruit trees and brooks but the only thought this person has is to climb on the top of the mountain. The person wakes up exhausted and disappointed because there was no way he could have gotten on the top.
A person has an ordinary dream but all the sudden realizes that a dream is happening. As this person realizes this decides to take different paths and change things that were meant to happen.
Some of these philosophies compare dreams with real life and death to waking up. Are there any other authors or philosophies (western if possible) that emphasize on dreams and how we could learn from them in order to evolve philosophically in life? (Not interested in interpretation of dreams or similar).
"What is life? A madness. What is life? An illusion, a shadow, a story. And the greatest good is little enough; for all life is a dream, and dreams themselves are only dreams."
Pedro Calderon de la Barca
