There could be more to your story, than what I see. But could one of the reasons be, that since you say you had hard time getting bad dreams out of your head, you made a decision to stop remembireng them?

Or, you were lucid dreamer as a child, but now, you may need to do some work in order to get your dreams and lucid dreams.

Keep a dream journal, think about your dreams often and be gratefull for them, so your mind understands, they are important to you. Good luck
