"Les rêves semblent réels quand nous y sommes. Ce n'est qu'au réveil que nous réalisons que quelque chose était en fait étrange."
— Christopher Nolan
Simplified Meaning:
When we're dreaming, everything seems normal and makes sense, just like in our waking life. Our minds accept the dream as real, no matter how strange things might actually be. It's only after we wake up that we can look back and see how odd or impossible the dream was. For example, in a dream, you might be talking to a talking animal or flying without wings, and it feels completely natural at the time. But once you wake up, you realize these situations are weird because they can't happen in real life. This shows how our perception changes once we step out of a situation and look at it from a different perspective. In everyday life, this means that sometimes we may not notice odd or problematic things while we're in the middle of them, but taking a step back can help us see the reality more clearly.
