Since I started invoking archangels I have been having some sensations at some point of almost every ritual in which I called an archangel. It feels like itchy sensations at different parts of my body, sometimes it's a tingly brush against my skin. In my rituals I don't see or hear the archangels, but I get these sensations. Does anybody else experience it ? And if so, then what do you interpret these sensations to be ?
