The short answer
Dream interpretation is not prediction and not diagnosis. This article separates what sleep research observes from what popular interpretation associates with the theme.
A cockroach triggers disgust before fear. Disgust is an emotion with a clear job: keeping distance from things linked to dirt, contamination and disease. No surprise that the insect we most associate with rubbish shows up in dreams loaded with that feeling.

Why it appears
Anyone dealing with an infestation at home, living near old sewage lines or spending the day cleaning cupboards is more likely to dream about it, under the same continuity hypothesis that explains most dream content.
The practical reminder
If the theme keeps returning along with real sightings, treat the cause, which is almost always the same: accessible food and moisture. Storing food in sealed containers, not leaving dirty dishes overnight, sealing drains and cracks and keeping the bin closed solves most cases.
What folklore says
Popular readings tie the cockroach to money, to dirt or to a problem that keeps coming back. The meanings change from region to region and predict nothing.
