You are being led down a dark path...so that you are emotionally available to demons. Those are the voices you are hearing. The only way to get rid of the demons is to proclaim and profess faith in Jesus Christ. To proclaim that His death on the cross was payment for your sins. Call on the Holy Spirit to dwell within you and the demons will never come back.

I know this may sound like tripe. It may sound like the above is some "canned" answer. Please, do not take it as a canned answer. Please do try to ask Jesus into your life. The whole MKULTRA stuff is satanism in disguise. The only way to get rid of satan is by Jesus removing him and Jesus coming into your life.
