I also use the "looking past people" or "looking at the floor" trick. I was never able to do those magic eye things, so I can't really see the relation, but I understand what you're talking about. I also try to remind myself that just looking at the person is usually enough to assure them that you are listening, and often find myself focusing on either their hair or their mouth. Since I've become more concious of the fact that I don't make eye contact I've been attempting to do it more, but, as you have said, it's very overwhelming. I don't think that it's sensory overload in my case, though I'm not exactly sure what a sensory overload entails. For me, when I look at a person's eyes it's more that I am overwhelmed by a lot of confused thoughts of trying to understand what a certain look means, or whether or not I am holding the person's gaze for too long. When that happens, I can't listen to what the person is saying, so I try to make what I consider to be a minimum amount of eye contact. A friend of mine used to get angry at me for not looking at her when she talked, because she thought I wasn't paying attention. For me, it's the opposite, though- if I'm looking at the person when they speak, I'm less able to pay attention to what they are saying.
