Well, when I wake up, I sometimes remember my dreams and there really no different then day dreaming. When I'm in the dream, I can open my eyes whenever I want but I don't usually know I'm dreaming, and also seems very dull, like I can still see darkness in my room, but seeing a dull movie too. When I lucid dream, I feel like I'm actually in the dream.

Why is that? and how do I make it better?
