During 2016, when I was dealing with some trauma in therapy, I would wake up every morning for a while knowing my extreme anxiety was caused by anxious dreams (but usually not remembering the details of the dream--I tend to remember more details towards the end of an ordeal/anxious period). I would wake up with a severe panic attack and sometimes it would take hours for it to settle down. I don't know if this describes any of your anxious feelings in the morning or not....
