Maybe it's not the same but I daydream quite deeply when I'm doing things that have no verbal component. So like when I'm driving, I'll start planning stuff out and coming up with ideas (often quite visually, too) then "snap" back and think.. I don't remember any of the actual driving. It's common enough to have a name though – https://en.wikipedia.org/wiki/Highway_hypnosis – and I haven't had any accidents. Curiously, putting on talk radio or podcasts helps as it prevents the daydreaming.
