Their presence became "outward internally", to coin a phrase, roughly a year ago. In my case, this is a cooperative operation that is working with local law enforcement. I had a friend describe the exact same experience some years ago. I didn't believe it at the time, now I know it's true. Their have been laws passed in America that allow the classification of citizens as enemy combatants. All that it takes is the accusation or false accusation. This opens up the citizen to "The Program": 24 hour a day surveillance, negative multi-voice mantras that revolve around first and foremost: Fear
They know what you've done
They are going to expose you
Everyone knows or is going to know any embarrassing or damaging thing in your past
You are in danger
You are anything unsavory in your subconscious
You have no reason to live
In my case, and my friends experience sleep deprivation is a, if not THE key component. That is torture 101. The next factor is using your subconscious against. Our subconscious free associates thoughts and reactions that can be manipulated. This is another key factor. Trying to convince you that something in inherently evil or wrong with your internal mind and reacting to free associations that many times they have actually cultivated.
What I'm doing:
I am a believer in God. I am a Christian. So I pray, listen to the Spirit, use positive prayer, affirmation and meditations that are what God says about me, my purpose and future.
Use a sleep aid as necessary.
Continue to participate and stay involved with the world, friends, family, pets,activities and work etc.
Today was a day well spent, if they ever succeed and carry out any of the threats they make against me, then I spent this day well.
