Please be aware and look into targeted individuals. It starts with very loud ringing in the ears, then you hear a voice. DO NOT ENGAGE WITH IT UNTIL YOU VERIFY WHERE IT COMES FROM. The voice (s) will be nice to start with, then they will start asking you personal questions. DO NOT ANSWER. This is widespread please go research. People end up being diagnosed schizophrenic because it gets to be 24 hour torture. It is not psychic, it is humans using advanced technology. Hallucinations, followed by energy running through your body, which gets painful and it is used to correct your thoughts or behavior or both.
You will end up isolated from friends and family, they try to convince you that you need to hurt others because they are hurting you. You may have 4th dimensional experiences.
They will never leave you alone if you let them in. Please, don't rush towards contact with psychic entities without very careful consideration. You will be awakened every night, if that is they let you sleep at all. I went fourteen days without sleep, and felt I was in another dimension. Many weird experiences that seem so real, beyond real. I fell for it, thinking this was what I had worked for so many years to achieve, until the abuse started. Not all contact is psychic I have learned.
If it does happen, please take a course on clearing the mind of all thoughts, they impersonate your own thoughts, try to get you to do things. As I speak my head if full of energy movement, as is my base chakra. Angels, guides, archangels, Jesus, whatever, won't do you the slightest bit of good if they snare you in.
I can dismiss them now, after 18 months, but they still keep trying. Imagine, no peace at all, ever. Take great care.
