Even if you don’t remember your dreams, they may well still be helping with maintenance of your noggin in the middle of the night (depending on your sleep schedule).
Very vivid dreamery is still there, 50 years later. Not haunting, lucid. It probably remains to be seen whether that’s good or bad. Places, faces in the abstract. Even during short naps.
Never have had a nightmare, just certain days/episodes while awake at work. Yikes.
Here’s hoping yours are sweet and helpful.
