One of the few dream animals whose traditional meaning flips completely depending on where the reading comes from, which makes your own reaction the most useful part.
Few dream animals split as sharply along cultural lines. European and North American dream books have generally handled the rat as a pest image, tied to spoilage, to suspicion, and to a problem in the walls that nobody has dealt with yet. In the Chinese zodiac the same creature opens the twelve-year cycle and stands for wit, resourcefulness and arriving first, so anybody raised with that association meets an entirely different animal in the night.
The Western line is not mysterious. Rats have been associated with stored food going bad, with outbreaks within living memory, and with the discovery that something has quietly been under way out of sight for a long time. That last element is the durable one. The expression about smelling a rat exists because the animal became shorthand for a suspicion that cannot yet be proved, and rats in a dreamed kitchen or cellar are reported most often by people who feel something has been going on beneath them.
It does not follow that the dream is evidence about a particular person. Treating a night image as proof of somebody else's behaviour is a reliable way to damage a relationship over nothing at all.
The other tradition is every bit as old. Folk tales in several regions hand the rat the winning role, outmanoeuvring larger and stronger animals by paying closer attention than they do. Laboratory work later made the animal a byword for intelligence and adaptability in a completely different register. Where that is the association in the room, the same dream reads as ingenuity and survival under pressure rather than as decay.
Somebody who keeps rats as pets meets a friendly, curious creature at night. Somebody who has fought an infestation in a rented flat meets something else altogether, and no reference book can tell those two apart from the outside. The dependable question is what you felt while the rat was there: disgust, alarm, indifference, even affection. Plain triggers are worth ruling out first as well, including a real sighting that week, a documentary, or building work next door.
