This has been bugging me for quite a while now, so hear me out. If it doesn't make any sense, tell me.
As a filmmaker, I'm truly unsure whether this is just my gift of strong imagination and aspiration or whether it's synesthesia or something similar which has a specific condition name for it.
I've researched about synesthesia, but I think what I experience might be something similar or irrelevant. It's like whenever I listen to a song, read a book, or watch a film, suddenly, and without warning, I somewhat experience a thought/daydream, which can somewhat contribute as an idea towards making a film, and it will constantly bug me until I write that idea down. Sometimes it happens to something relevant like I listened to Led Zeppelin's "Babe I'm Gonna Leave You", and completely envisioned a music video-esque short film about a man leaving his woman, in a span of 3 minutes, just when the song really kicks in.
I can also somewhat hear music and put it to a colour, and sometimes refer certain names to certain objects. I think this might be synesthesia though.
Bear in mind, I'm trying to explain this as much as I can, but it's really difficult to word it, in a way you can help me understand what it's all about.
