Have you ever woken up from the most vivid, unbelievable dream — flying, talking to someone you lost, standing somewhere that doesn't even exist — and by the time you're brushing your teeth, it's completely gone? Not faded. Gone. Turns out there's a real, chemical reason your brain does this to you almost every single night.
