I have also been dealing a lot with negative energies, of course in the physical realm but most strongly on the Astrals. Partially own baggage, but also other entities. It is necessary however, to discern whether it is our own energy or somebody else's. Many times already I felt fear energy or negative energy but wasn't sure whether this is really negative energy emanating from another source or whether this energy is simply my fear energy and the source has nothing to do with it. "Is this entity really negative or is it just my fear which I feel?" Over time I got a much better handle on this and even if its truly negative energy from somebody or something else I now feel somewhat bored by it, for they draw their entire power from one's fear. I might feel fear for a minute or so but I also know that nothing can happen...
