"Rêver est une sorte de maladie mentale ou plutôt quelque chose de plus couramment associé à elle."

Simplified Meaning:

Sometimes, when people dream, it can seem strange or disconnected from reality, almost like an illness that affects their mind. Think about when someone spends too much time daydreaming. They might ignore important things in their life, like work or relationships, because they are lost in their own thoughts. This doesn't mean dreaming is bad, but it can be similar to being a little out of touch with what is happening around them. For example, imagine a student who dreams of becoming a famous musician but doesn't practice or study. They might fail their classes because they're always thinking about their dream instead of doing their homework. It's not that dreaming itself is harmful, but if it takes over too much, it can cause problems. To use this advice in your own life, it's good to have dreams and goals, but you should also stay grounded and pay attention to your responsibilities. Balancing dreams with action and reality helps you achieve your goals without losing touch with what’s important right now.
