Kind of.. low vibrations conscience can manifest as something similar, even in the bible there's something like it .
Discussion
It would be something akin to the soul, if you are hurting, feeling revenge , anger , despair you lower your vibratory pattern , so that it can become sort of corrupted if you have already passed away . This would be something that they used to call demons , an existence , a conscious like ours , but it can be recovered .
it also means that it can do you harm if you let it.
