Answer
It indicates a dangerous loss of alertness due to fatigue; you should stop at the next safe, legal location to rest and refresh.
Not remembering the last few miles or junctions is a major symptom of severe driver tiredness and impending micro-sleep. The only safe and effective response is to leave the road at the next safe, legal place (such as a service area or designated lay-by) to rest, consume caffeinated drinks, or take a short nap.
