Mindfulness and lucid dreaming

One thing I notice quite often after practicing mindfulness over a long period of time (like when I go into the woods for the better part of a day) is the frequency of lucid dreaming increases astronomically. Such as last night, I was dreaming that I was standing in a street in a cartoonish-like city, and I instantly knew it was a dream. In fact, I remember having an awareness that it was a dream before the scene was created. One trouble I'm having with lucid dreaming however is that I struggle to control the content. I wonder if other people that practice mindfulness experience a similar thing, I also wonder if this is a good or bad thing. Another strange thing about this dream (and others) is that I still have my sense of self (I understand the dream is a process in my head, and I can create an awareness of my actual body) and memories of reality.
