Why do some people always remember their dreams, and others don't? Science and psychology explained

You wake up, and the entire dream unfolds in your memory like a movie scene. But you also have that friend who swears they can’t recall a single dream. You, on the other hand, can describe last night’s dream in vivid detail. Well, that’s not ‘nothing’. For decades, neuroscientists have tried to understand dream recall , related brain differences, sleep chemistry, and trainable habits.
