Some POV confusion (involved in said dream, or watching?). As if watching a first-person 'film'/nrarative, with some (guy?) telling the tale of some adventure, with him (due to having a lot of disposable income?) buying a cheap crappy submarine from an airline company (as if they also carried these specialty accessories), into which he and a client of his entered. The rest of the story wasn't clear, but they both were in it for some purpose related to some case of his. He was definitely Annoyed by this 'cheapness' as he kept mentioning it.
