Video narration
Why would Lina dream she was swimming in the sky, chased by a fish in pajamas? It sounds like a pretend game made from familiar things: swimming, clouds, and one very underdressed fish. Then Lina wakes up and asks, "What has my brain come up with now?" Here's the surprising part: while you sleep, your brain stays busy. It works through information and memories. Sometimes, images and ideas get mixed together, making a wonderfully odd dream. That explains how dreams can become strange, but not exactly why Lina was swimming in the sky-or why that fish needed pajamas. People don't always remember their dreams, even the funniest ones. So, what made this one? Her sleeping brain mixed bits of information and memory into a surprising scene. But the exact recipe for sky-swimming Lina? That's still a mystery, pajamas and all.
