Dreaming about a mouse
Dreaming about a mouse is traditionally read as something small that has got in — the domestic version of the rat dream, with less disgust attached. No survey has measured how often this one occurs, so we give the reading without a frequency — only 19 of the dream themes here have a published figure at all.
The psychological reading
Reported during periods of small persistent irritations rather than single problems, and the mouse is usually glimpsed rather than confronted.
When it turns up
Why this dream arrives when it does
The mouse is the domestic version of the rat dream with far less disgust attached: something small has got in. It is reported during periods of small persistent irritations rather than single problems, and the animal is usually glimpsed rather than confronted.

The version matters
Different ways this dream shows up
The version carries most of the information.
A mouse being hunted by a cat is a specific and reported variant, and reads as watching something vulnerable that you are not intervening for.
A mouse glimpsed and gone
The commonest form. It reads as noticing something is off without being able to fix on what.
An infestation
Accumulation. Dreamers report the evidence — droppings, noises, chewed things — more than the animals.
A white mouse
A searched variant, and it reads as domesticated rather than invading: something small that belongs, or was let in on purpose.
A dead mouse
A small problem resolved without satisfaction. Reported as flat rather than sad.
A mouse in food or bedding
Intrusion into what should be private or safe. It follows situations where small annoyances reached somewhere they should not.
A cat and mouse
The pairing makes it a dream about pursuit rather than infestation, and which one you identify with is the useful question.
Commonly claimed, and wrong
What this dream does not mean
Mouse dreams are not a sign of timidity in the dreamer, which is the usual online reading and rests entirely on the English idiom. They track small intrusions.

Questions about this dream
What does it mean to dream about a mouse?
Usually something small that has got into your space — an irritation rather than a threat.
What does a white mouse mean?
It reads as domesticated rather than invading. Dreamers report much less disgust than with ordinary mice.
Is a mouse dream about being timid?
No. That reading comes from the phrase quiet as a mouse and not from anything dreamers report.
