jnean,
That sounds like a scary time, I'm sorry to hear that. I hope some of the fear has left you and you feel better.
I've had similar experiences before two, which for me I feel fall into two categories. One is when I'm experiencing a flashback any people around take scary faces, of all sorts, usually linked to how Im feeling or what the flashback contains. They become characters in a part of the flashback I guess. The other is when I'm very uncomfortable, or unsure, or feeling something isn't right, then people's faces change and 'reveal themselves', so I can know much more clearly what to do, or who they are. One experience I had was with a housemate I once lived with, she seemed like she had a 'hard life', and one day her face appeared all scarred and worn. It actually led me to feel more sympathy for her, in this instance. Of course with the experience you are saying this might not be the case at all. I guess I agree that any physical perspective or metaphor, like scars, may not be necessarily bad.
Good luck with it.
