Dreaming about a rat
Dreaming about a rat is traditionally read as something unwanted that has got inside — rats in dreams are almost always indoors. 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
Disgust rather than fear is the dominant reported emotion, which separates this from snake or spider dreams and points at contamination rather than threat.
When it turns up
Why this dream arrives when it does
Rats in dreams are almost always indoors, which is the whole point: something unwanted has got inside. The reported emotion is disgust rather than fear, placing this with contamination dreams rather than with predators.

The version matters
Different ways this dream shows up
The version carries most of the information.
A single rat and many rats are different dreams: the second is reported during periods of accumulating small problems.
A rat in the house
The most searched form. It reads as an intrusion into private space, usually one you suspected before you saw it.
Many rats
Accumulation of small problems. It is reported during periods where nothing is catastrophic and everything needs attention.
A white rat
Domestic rather than wild, and dreamers report far less disgust. It often attaches to something unwanted that turned out to be harmless.
A rat biting you
Contamination turning into injury. It follows situations where an ignored problem finally cost something.
Killing or trapping one
Dealing with the symptom. Dreamers frequently report knowing there are more, which is the useful part.
A rat watching you
The quietest and most unsettling version. It tends to track suspicion about someone in your own space.
Commonly claimed, and wrong
What this dream does not mean
Rat dreams do not identify a traitor, which is the standard online claim and rests on nothing but the English slang. Disgust is not evidence about anybody.
