Why we dream (and what your brain doesn’t want you to remember)

Your alarm goes off. The dream is crystal clear… and three seconds later, it's gone. That's not bad memory. Your brain may be doing it on purpose. Why do we dream, and why do we forget our dreams so fast? This is the psychology of dreams, backed by real sleep science and neuroscience: what your brain does during REM sleep, how dreams work, why some people remember dreams every morning while others never do, how dreaming may work like overnight therapy, why the "exam dream" keeps coming back, when nightmares and sleep paralysis are worth paying attention to, and how scientists actually talked to people in the middle of a lucid dream. Forget dream dictionaries. The real meaning of dreams comes from your own life. This is the science of dreams, and of why we dream, explained the WiredMind way. 👇 Your challenge: tomorrow morning, before you check your phone, type three words about your dream. Drop them in the comments. I'll read them. 📚 Studies mentioned: Horikawa, Kamitani et al. (2013), Science: decoding dreams with fMRI Eichenlaub, Ruby et al.
