Well this isn't a dream experience, but I did have several times what can only consider an attack. Was just sitting down when felt this serious pain around my arm and looking down it was bruised to the bone, hurt for days and don't know how it got there, but it was all the way around the arm and half an inch in width. I've also gotten out of the shower and suddenly I couldn't breath like being smothered, and than it went away as suddenly as it came. Another time I started to feel something tighten around my neck and squeezing off my air, even struggled automatically with nothing there. Don't know if there is a condition that can cause this, but I have a hard time in believing in ghost, or demons. More won't talk about, but I feel something is not born evil, evil is an act. I don't always feel a malevolent attack against me. Lucky to be alive.
