if there is a connection between these and the beliefs of "reaper" (broad descriptin for whatever these may be)..type entities, it dousnt take anything to manifest. complete different type being than spirits or others. they have a specific purpose and free reign to achieve it. but the intense impression it makes and the energy expended to those with abilities could be massive. and someone with abilities may not be their intended host. one of the reasons ive had an interest in these type beings does come from an experience i had long ago. i didnt see anything, no shadow figure, no hatman etc... just a feeling, but there was no doubt what i was feeling. and it was terrifying,... and draining. but even still i have to ask myself if it was real. the logical side wants to forget it and let it go, but then theres something that i cant deny. so am curious on this topic. i dont hunt ghosts or deal with what is on the other side of the veil. but this does get my attention and like hearing others opinions and ideas concerning thisAs well as these things feeding off our energy. It takes something to manifest, so why not bleed some from their intended host.
