Something between hypersensitive and empath... There are people like that. You could envy them or pity them. Depending on your point of view.
Since this phenomenon was only scientifically investigated and proven quite late (I think it's only been a topic taken seriously for 5 or 6 years?), I find it quite interesting that "Star Trek" with the Betazoid (Deanna Troi) drew attention to this kind of emotional communication very early on...
Haven’t watched Star Trek but read about Betazoid to understand your reference better. It’s the same way with loners they also sense emotions. I wouldn’t pity them cause that’s how they only know to be.
