I have noticed over the years that certain people look like carbon copies of other people (not blood related). People tell me that my youngest sister and I look very much alike. When we are together they just sort of stare at us for a long time. Maybe trying to place what it is that looks so similar. We a totally different types though. I cannot find one person in this thread that resembles me. I might not be objective enough to do this.
One thing I have noticed in people with strong Ni (irl) is they seem to have one eye that looks right through you and the other eye seems to be focused somewhere off in the distance. Not like a true lazy eye but something similar. It looks sort of hazy or unfocused/dreamy to me. Not sure if I am explaining it how I see it but I like the way it looks. I have seen it in a few people here too.
