trying to communicate with someone who doesn't speak my language I would resort to symbols and charades. I would point to things and say words till the person made a connection and understood my meaning. Often we are visited in our sleep by wandering spirits, so it's possible one stopped in to say hello and used the face from your memories to represent itself. this is more likely if you awoke scared than if you awoke calm as the part of your mind which they contact is very deep and closely connected to the instincts part (controlling fear).

Still the eye is interesting. It reveals more about you than anything. the eye is the window to the soul. you have a skill for seeing. check out the pic = 10000 words and look deeply into the eyes of people. watch them come alive.

verbal language is on a very small % of communication. most of what we communicate we do through body language. Still deeper is the first language, the one we speak before we are born and all share. Most forget this as they learn to speak as children but spirits still use it and so does the inner self. This gets translated very poorly by our mind into dream symbols.

Hope that helped, i'm running out the door so didn't get a lot of time to think before typing.
