In regards to eating meat

[native]

When I ate the meat, I was absorbing all the fear that the chicken or fish had at the moment of slaughter. That fear attracted negative entities who feed on fear. This had been happening all along, but after cleaning my system by being a vegetarian all those years, I was able to perceive and recognize it.

That's an interesting thought, but could your nightmares simply have been a reflection of the turmoil within your consciousness? Given that you have such strong feelings on this subject, the fact that you had to compromise your beliefs and put a strain on yourself emotionally (I imagine you weren't happy about having to eat meat), your emotional state could have opened yourself up to a negative state. Your dreams perhaps were simply reflecting the disharmony you felt within yourself.
