I too had those dreams. I was in there in the late 80's. The dreams are VERY infrequent now.
They were always about being accused of doing something wrong that I never did, and no one believing me. And I also would wake up completely disturbed and almost frightened. Then, when realizing that I was safe in my own bed in my own free-to-come-and-go-as-I-please world, it got better. Now, all these years later - this is the good part - when I have those dreams, they always end with me escaping. Escaping and being free and feeling the surge of power one can imagine from being able to run away and run fast and well and smart enough to not get caught. I always get aways at the end of my dreams, they are very liberating. And those dreams are welcome, they're like some sort of redemption. The dreams will get less and less for you, and they are important and a sign that you are healing from the experience.
