So i was talking about dreaming and lucid dreaming with my girlfriend...and it seems like she does it often! Besides that, she claims she has a whole detailed world that she has worked on that she goes into when shes lucid and even told me in detail every part of the place. Would this just be a part of the unconscious mind that has created a personal "realm" for the person to explore in? Or would it be something created like in the astral?

*edit* and she also states that its the locations in her personal realm that spark her lucidity, like "oh theres my lake in my world" and become aware she is dreaming, and would leave items around like a flashlight to turn on to see if she is dreaming or not
