What's triggered the new onset? Has something happened? Eating any different foods? Not eating enough? Usually when things like this go away and then comeback, there is a trigger, maybe one you can avoid??

BTW, for some people, the really deep sleep that comes from sleep meds stops them from dreaming, or at least remembering them. If it gets too bad, you may want to try tylenol night time for a few days and see if it help. Not for too long though, as sleep aids can get pretty darn addictive, as you well know Dr. B :) (foolish me giving medical advice to a medical professional)
