Why can't you remember your dreams?

Tonight you will fall asleep and your brain will run a full feature film. Flying. Chasing. Conversations with people who are not there. Two hours of vivid dreams. Then the alarm rings, and not one scene survives. You know you dreamed. You can feel it. But you cannot remember a single detail. Where did it go? What this covers: The 1953 Chicago discovery that gave science its first measurable way to catch a dream in the act The 90-minute sleep cycles that open four to six dream windows every single night The famous 1977 theory that says your brain builds dreams out of random neural static The 1981 finding that your brain's memory chemical goes silent exactly when you dream The rat study that revealed sleep replays your day but leaves the dream behind Why some people remember dreams every morning and others never do — it is not talent, it is timing The Stanford experiment that proved conscious awareness inside a dream is measurable Forgetting your dreams is not a conspiracy and not a broken memory. The science points to something far more mechanical. And it turns out you can change it. What is the wildest dream fragment you managed to hold onto this morning? Tell us in the comments.
