I have had dreams like this for quite some time and have never been able to find any sort of information on them, and if anyone could tell me if it is in fact lucid dreaming or something else would be nice. Let me preface this by saying that I almost always remember at least details of my dreams upon waking, if not the whole thing. So my ability to recall dreams is very good. Sometimes when I dream, I become aware that I am dreaming a detail from another dream, usually a place, and I remember that dream while inside the dream which actively changes the current dream to fit the old. As such, I tend to have dreams that can pick up from where the previous one ended, in the same locales and "repopulated" with the same people from the last dream. Sometimes new people. And sometimes I dream these epic dreams, maybe once a year, of extremely complex actions and realistic dialogue and they are very vivid and colorful and seen like real life. And these huge quest kind of dreams happen maybe every eight months, but sometimes I will have smaller dreams that continue those as well. I'm not sure if they are lucid dreams or whatever because in the dream, I do not think I am fully aware of it being a dream, I just know that I've dreamed it before. It's like having a memory for dreams while dreaming.
