This means don't go looking for trouble. If things are going well, be satisfied because if you 'wake' the dogs, problems will arise.

Primates awoken while dreaming, continue for a period of time in a mixed sleep/wake mind state. A similar mixed mindstate (as evinced by brain wave studies) has been linked to some hallucinatory psychosis and violent aggression.
