No more nightmares?

As I woke today I found myself thinking, and what I thought was "I can't remember the last time I had a nightmare".
Nightmares were a regular occurrence for me growing up, and even in my twenties and thirties I woke up screaming far too often.
I'm not sure why my nightmares have stopped - maybe my getting into the memories of my rape has paid off, maybe there's another reason, but I'm grateful for the change, regardless.
