I see them frequently, I know when I'm going to see them. I can feel them before they come. Since I was a little Kid growing up in MN. I could always sense them, then I would see them! I'm in my 40's now, and I feel them around me all the time. Many times it's such a strong presence I get nosebleeds and extreme chills from them.
It's like they know I can see them, so they torment me!
