"Un rêve qui n'est pas compris reste un simple événement; compris, il devient une expérience vivante."

Simplified Meaning:

When you have a dream and don't make an effort to understand it, it's just like any other random event in your life. It doesn’t mean much and you might forget it quickly. But if you take the time to think about the dream and understand what it might be telling you, it can become something important and meaningful in your life. Imagine you have a dream about walking through a beautiful garden. If you just wake up and ignore it, it’s nothing special. But if you think about it and realize the garden represents your need for peace and relaxation, you might decide to spend more time doing things that make you feel calm and happy. In real life, it's like when you have an idea or a goal. If you don’t work to understand why it’s important or what you need to do to achieve it, it’s just a thought. But if you explore it and plan how to make it happen, it becomes something real that can change your life. So, by reflecting on your dreams and ideas, you can turn them into meaningful experiences that influence your actions and bring positive changes.
