Why Do We Dream?

Dreamy, surreal visual: a person floating in a starry sky, surrounded by swirling colors. Camera orbits around them slowly, with a soft glow. Cut to a realistic brain scan with rapid eye movement (REM) highlighted in red. Overlay text: 'Your brain is more active at night than when you're awake.' Then a sequence of quick cuts: a person running, a childhood memory, a flying dream — all in a hazy, ethereal style. Narration: 'Dreams might be your brain's way of filing memories — or predicting the future.' End with a close-up of a sleeping face, eyelids twitching, then a sudden wake-up with a gasp. Style: cinematic, low-key lighting, with a mysterious tone.
