Ever since I can remember, I've had crazy, unrealistic dreams that are incredibly vivid and memorable. I almost always remember my dream(s) from the night before - sometimes they are so vivid that throughout the day I get confused as to if they happened in real life or were just a dream. However, my boyfriend always has very normal (dare I say boring) dreams and can rarely remember them. I've met many people like this. Why is there a difference in how people dream and if they remember them or not?
