I'm going to talk about my dreams.
First of all, I sometimes have dreams where I can go and revisit places where I'm already been "In other dreams". In those dreams I just explore those old imaginary places and I also have the opportunity to map them, explore them and also remember the original dream where they appeared. 2 days ago I revisited the "Tower of Knowledge", place where I had a dream 4 months ago, and some things get stuck since the original dream.
Isn't that interesting? Revisiting places from previous dreams.
Other thing that happens usually in my dreams: I'm watching a movie on TV and I can feel myself watching it, but after a while I end inside the movie, and the most weird thing, I completely forgot that I'm was watching movie, like if I'm was always already there.
I once dreamt that I'm was watching movie with dudes entering a mine, but I'm later finded myself in that mine and the protagonists disappeared, leave me alone in that mine, with no idea that I'm was just watching movie and that I'm was already traped in the mine, looking for an exit.
Does that happen to you too?
