The first part of your comment reads like my own thoughts. I still find myself incorporate new fictions into my mental canon. Over time the framework has changed significantly, but its roots are still noticable. Some of my earliest memories are of me playing around with this fantastical dreamscape. Nowadays I generally dive into these sorts of day dreams whenever I'm walking/biking alone, or showering. Music or white noise can help me get into it more.

Neural interfaces will be a game changer. I'm so excited for them.
