I don't know if this will work for you or not, but I once had a dream that a guy was threating me. For some reason I kissed him to change the mood. Then he started kissing me. I realized this was a dream and became lucid.
Another time I had a dream that my dad was saying he wanted to get rid of us. I said I love you and he said I love you back. Then I realized it was a dream. So I guess you could try changing the mood like that then you can get away. It's worth a try anyway if nothing else works.
