There are beings not of this world. They call themselves “The Sumi”. Now that you know - they also know of you.
During WW2, Nazi medium Maria Orsitsch made the first (recorded) successful telepathic contact with them. After years of communication at the behest of her SS superiors she was abruptly taken in 1945 and never seen or heard from since. It has become clear that they view us as little more than lab rats to be studied from afar through means unknown to us, possibly powerful psychic abilities or technology unheard of to date. Anyone who knows about them is now considered a threat to their “tests” and someone or something will be sent after you.
In less than a day, you’ll start experiencing the sensation of not being alone anymore, anywhere. As it gradually homes in on your location through time and space you’ll start to catch its reflection or see its blurred outline becoming gradually clearer over the course of a week. After that it’ll start making physical entry into our reality and in less than a month it’ll grab you and you’ll never be heard from or seen again.
I write this so that someone might find a way to stop them, if only as a last desperate act. God help us all!
