Nice link JustBe:

We can read in it : "Psychic empaths do not need to have this kind of interaction or awareness. Of course, an empathic person will also pick up emotions through communication and interpersonal interactions too, but they don't need it. They are picking up on a person's 'vibes'.

An empath can sit in a room and be perfectly fine. Some stranger happens to sit behind him or near him, and all of a sudden the empath starts experiencing new emotions that seem to come out of left field. The empath doesn't have to know or talk to an individual, doesn't have to be looking at the individual, or even know that the individual is there. An empath can even pick up emotions from a complete stranger sitting on the other side of a wall."

For an empath its a curse when one believes the "vibes" felt coming form others comes from her or him. It's a gift in knowing directly all the different ways to be in this world others have.
