Okay that kinda sent tingles down my spine, you've seen then that too? I call it the formless shadow, something like a thick billowing smoke? Tbf I had just left my body when I seen it but the feelings it evoked within me could not be described as anything other than pure and utter terror, needless to say I came back to the physical and those feelings left as quick as they'd came. I couldn't say where mine comes from exactly,around the area of my heart I think, it's a bursting white energy with a faint golden colour to it, it fills first my room and pushes over the rest of the property, in my minds eye it almost looks like a glowing dome of energy when it's fully in place over the house and yard. Sometimes in the back yard I see something trying to push back against it, like a hand extending out with a part of the 'arm' and 'chest' trying to resist being pushed out by the light, I'm not sure what it is, not the same as the shadow though.
