Sara-
While I haven't had these specific dreams, I have found that, in general, my dreams will mirror what ever is troubling me. And, while I am not a therapist, I would venture a guess that you may be struggling with the whole facial paralysis thing. I can offer that, in my case, talking to my husband and family about my fears and uncertainty about my face (and I've had PLENTY of both) really helped me in coping with it. I also regularly talk to another women who had this surgery about a month after me who is also dealing with facial paralysis and find it very helpful to talk with her about it.
I don't know if this helps, Sara, but hopefully you'll find some peace with this. I know, firsthand, how hard it is to have a face that doesn't look "like me" anymore. However, as you know, you are still you inside.
hugs to you,
Debbi
