Hi Lizzie,
A psychic vampire is someone who for some reason just "sucks the life" out of those around them, especially people who are sensitive. Some of these individuals are aware of the effect they have on people, some are not. Being around them can cause nervousness, fatigue, etc... They can even appear to be seemingly chirpy "people persons", but when you scratch beneath the surface they are very negative people. In many cases, they almost seem to gain strength by the effect they have on others, almost "feeding" from them.
I generally try to avoid this type of person whenever possible. In some work situations, it is almost impossible. I had one on my last teaching job, the lady was actually my aide. In my situation, I was able to "generously loan" her to the front office frequently. Others may be able to give you more spiritually oriented advice on protecting yourself from such individuals, but the solution I've always found most effective is to stay the heck away from them!
