Dreaming about a roach
Dreaming about a roach is traditionally read as persistence you cannot negotiate with. Cockroach dreams turn on the fact that the thing keeps coming back. No survey has measured how often this one occurs, so we give the reading without a frequency — only 17 of the dream themes here have a published figure at all.

The psychological reading
Disgust rather than fear is the reported emotion, which puts this with rats rather than with snakes — the concern is contamination, not danger.

When it turns up
Why this dream arrives when it does
Cockroach dreams are about persistence rather than danger: the thing comes back regardless of what you do. The emotion people report is disgust, which puts this dream with contamination rather than with threat.

The version matters
Different ways this dream shows up
The version carries most of the information.
One roach and an infestation are different dreams: the second is reported during periods where a problem has stopped being containable.
One roach
Containable and still unpleasant. It tends to follow a single recurring annoyance — a message that keeps arriving, a bill that keeps returning.
An infestation
The most common version. It arrives when a problem has stopped being containable and has started to define the space.
Roaches appearing when the light goes on
Concealment exposed. It reads as suspecting something for a while and finally seeing the extent.
Roaches on the body
The version most tied to physical sensation in sleep. Check bedding and skin irritation before reading anything into it.
Killing them without effect
Effort that changes nothing, which is the core complaint of the dream. It follows situations where solving one instance does not touch the cause.
Roaches in food
Contamination of something that should sustain you. It is reported around situations where support has become unreliable.
Commonly claimed, and wrong
What this dream does not mean
Roach dreams are not a sign of dirtiness in you or your home, and they do not predict illness. The imagery is about recurrence, and it appears in people whose homes are spotless.
