I am talking about feeling other peoples feelings, you walk into a room and someone in that room feels your feeling literally as if it was theirs. Not empathy. I presume you are either unaware this is a thing or, don't believe this is a thing? It's typically one of the two. Some people have it strongly, some people don't seem to have it at all. Emotional Contagion is a good book although I don't think that is what it is, there is also this but I also don't think this is what it is
