Ok here is my other thread about another Super-Natural experience.
I would see shadow-like humanoid figures doing stuff(peeking from a door windowpane then running and staring from a distance), always looking at me out of the corner of my eye. But when I look at them directly they fade away. I have heard other people have seen them,but not as limited as me. I once saw one while walking that choked me and I felt it physically. But this one was a bit different. He was more tall and he looked cosmic almost. Splotches of purple,blue,and tints of red surrounded in black.
What are these?
