I'm usually not too consciously aware of other people's body language. I don't want to read, then interpret, then act on the interpretation of someone's body language consciously. However, I've noticed something and I'm extremely curious as to what it means. Whenever I really want to create an emotional connection with a person (usually girls I like) and open myself up, I find myself looking at her eyes intently and she looks into mine and we get a 'lock-on', if you know what I mean. And I noticed something I don't see when I'm talking casually to people and give eye-contact: Her eyes rapidly move from side to side. It's a very small motion, her eyes are still fixed at mine the whole time, but it's almost like they are vibrating. It's an unconscious motion, no doubt of that. I couldn't find what it means anywhere and I've seen happen this quite consistently. Is it heightened interest, discomfort (ouch), or something else? Anyone else noticed this?
