I've experienced the same with routine tasks such as showering or going for a run. I'll often put on a podcast or audiobook, but if I don't find myself actively focusing on the narrative, the daydream will be "louder" than what I'm listening to. I find I can go almost an hour with background noise I never heard before realizing I completely lost my place.

This phenomenon does not occur if I'm reading a physical piece of media, like a book.

I do it with books, too. If I'm not 100% interested in what I'm reading there's a very good chance I'll doze off into an elaborate daydream.

I also emphasize with the "louder" thing. Uninteresting things aren't as loud as my thoughts so I have to make an effort to suppress them.

I'm finding that I also empathize with what you guys are experiencing, but I never thought to call it a daydream. I guess I have a very fuzzy definition, now that I think about it.
