How grey changes the reading
The base reading of Mouse
A mouse in a dream is the dictionary's clearest image of a small thing that has gotten into a place it does not belong. A small worry inside an important relationship; a small lie inside a big honest situation; a small habit eating away at a sound structure.
The dream is rarely catastrophising. It is asking you to deal with the small thing while it is still small.
Where you often see it. A mouse in a kitchen. A mouse glimpsed in a closet. The dream uses the mouse for a small thing that has gotten into a place it should not be.
What it is not. A mouse is not always fear. The dictionary often reads it as the dreamer's intrusion-anxiety in small form.
Related in the dictionary. Read mouse with rat (its harder cousin), kitchen, and any scene of small unwanted presence.
