Summary
A sketch I drew once of what it looks likes when I (a psychic vampire) feeds. Low quality I apologize. But the tendrils that are used to latch onto and drain the target would look like that to anyone who is witnessing it. Would need to be able to see energy though. Its invisible to the naked eye. But for all the non-clairvoyants out there here you go :)
