My eye opener was years ago. Back then I had something diagnosed as "neck migraines" on the left side of my body. There is no way to describe the pain. Sometimes I would be down for days. During one episode a massage therapist who "sees energy" said "there is a demon on your left shoulder trying to take your head off.
It was cleared, and still, after all these years, I've not even had a headache.
Previously a skeptic on this sort of thing, I did some research. Here's what I came to believe:
Beyond our sight are forces that have the power, when we're unaware, to manipulate our existence. All the spiritual traditions speak of these energies, but modern man prefers to ignore the subject. In fact, we've been conditioned to think of all this as fiction. But it's reality.
These forces have been called demons, spirit oppressions, curses, implants, etc. (You may choose not to believe in or accept this. After all, we have free will.) These forces operate as a vibration, and take you into a low vibration cycle. Often this happens in small increments. Some signs of negative entity influence could be a decline in moral character, poor physical and emotional health, addictive behavior, any desecration of the body, selfishness, greed, base ambition, behavior that is mean, selfish, disloyal, or self sabotaging.
Hope this information is helpful-
