I think people who are empathetic pick up on this kind of energy fairly easily.
One example is for instance, my husband walked into the house after loosing a job (this was like 25 years ago) He did not say a word as he entered through the door, but the negative energy he was expelling hit me in the stomach like a sledge hammer. The despair was palpable, I said, "omg what's wrong". Then he told me he lost his job.
Wish Kass would come back and finish her thoughts here. Miss you lady...
