From one website:

Cockroaches
To see cockroaches in your dream, signifies your need for renewal, rejuvenation and self-cleansing of your psychological, emotional, or spiritual being. You need to re-evaluate major aspects of your life.

Roaches
To see roaches in your dream, represents an undesirable aspect of yourself in which you need to confront. Alternatively, it may be a pun for smoking marijuana. On a positive note, roaches may also be symbolic of tenacity and longevity.

From another website:

Ants, spiders and cockroaches, particularly when they appear in larger numbers or even stream out of a cupboard or the kitchen cooker, are danger signals of the highest order.

Cockroaches
Seeing and at times just thinking about cockroaches makes a person feel squeamish and repulsed. When dreaming about these dreaded insects, the unconscious mind may be hinting to the dreamer that he needs to reevaluate and reassess a major part of his life. There is never just one roach; thus, the areas of life that need cleansing and renewal may be deep and wide. The negativity or contamination that is represented by the roaches may affect a great deal of your life. Thus, this may be a call to clean your psychological, emotional, and spiritual self. (Also, examine your motives!) On a less dramatic note, cockroaches in our dreams may be associated with food and uncleanliness, so don't leave the dishes for tomorrow!

A call to clean my psychological, emotional, spiritual self. Hmm.
