Smallness is the whole of this symbol: a minor problem that has got indoors. What changes when there is more than one, and how the reading differs from a rat.
Smallness is the whole of this symbol. A mouse gets noticed in a dream for being minor, quick and somewhere it should not be, and readers have long taken it for a small problem that has found its way indoors: a worry too slight to raise, a cost too little to notice until the pattern shows up. One mouse and a great many mice are handled quite differently, and dreamers usually remember which it was.
A single mouse generally suggests a minor nuisance, and sometimes timidity, the dreamer keeping quiet where they might have spoken. Numbers change the tone completely. Several at once, or the sound of them inside a wall, suggests that a small thing has multiplied while nobody was paying attention, and that account appears in sources from wildly different periods. A mouse being hunted by a cat is usually read through whichever of the two the dream lingered on.
Dream dictionaries keep the two apart deliberately. Rats carry disease, betrayal and revulsion in most traditions, while mice carry irritation, fragility and a certain reluctant affection. A dreamer who cannot say which animal it was is generally advised to work from the feeling in the dream, since fear points one way and mild exasperation the other.
Some people keep mice as pets and find the image harmless; others have had a kitchen genuinely infested and find it anything but. A parent whose child adores a cartoon mouse arrives with yet another association. Here is a symbol where the dictionary is easily outvoted by what the dreamer has lived, and it should be.
Worth mentioning too: hearing scratching in the night is a plain and frequent cause of these dreams, and that explanation deserves a look before any other.
