After a few dreams' worth of vague internals, sense of scale, and rather sneaky mood, I can guess by the lighting and architecture that I might be dreaming about a surplus B'Rel-class, probably modified. First, a dream of encountering some annoying Pakled trying to mess with me and beaming them over a "gift" in the form of an antimatter charge several years ago, then carrying a (decidedly non-Starfleet) PADD showing a small cloaked ship in orbit around a planet I was on (with several D'deridex Warbirds looming in the sky above which I didn't want to mess with) in a dream last year, later a dream of boarding a small ship that had a "head" section containing the bridge, and now just last night a dream of a rather dingy ship interior, with worn tan surfaces and amber lights dominating.
