I used to have such an imagination when I was young: before going to sleep, I would always reimagine the movies I just watched or the books I just read, factoring myself into the story (often as a coprotagonist, not particularly OP but helpful in many ways), sometimes going a bit meta trying to explain my presence to the characters, tweaking their response, trying not to trigger the obvious self-doubting panic that would ensue if someone told you your reality isn't actually "real".
I even had a cross-universe canon for my character: I often had wings (watching Winx club as a kid helped), and sometimes took characters on a multi-dimensional ride in my magic hyper-technological flying car, big as a house on the inside, capable of traversing space and time.
I absolutely feel the same way about music, it manages to turn any world, even a simple concept into a fantastical and magical music video of sorts.
As I went on with my life I somewhat lost this ability, possibly due to the highly technical nature of my job and hobbies, however I still love reading and watching good fantasy stories, and sometimes, when I feel like it, I still fantasize by joining the story and aiding the main characters in saving the world (and music still can transport me away to another world, like before).
I have often considered the enormous power, and just as enormous limtations of modern creativity tools.
I honestly can't wait for neural interfaces: when everyone will be able to extract images and audio directly from their brains.
It will truly be a revolution for the media industry, a change as big as the introduction of computers.
It will also give way to haunting new aspects of copyright law: what happens if someone publishes a YouTube neural video that uses copyrighted characters, do we prohibit people from even thinking about copyrighted IP?
Do we beam films using widevine L0 DRM directly to people's brains, immediately removing all memories of them after they were seen to avoid copyright infringement?
Those will truly be interesting times, and I would really love to live to see them.
