So I did a little research about them, Most of them says that a familiar is a Witch's spirit/animal guide/servant some says they're demons. They have so many different definitions but they share the same concept, it is something that guides a witch or someone. All I have found are just dots, and I want to connect them... I really don't believe that they are demons because we all know that people like to call anything that is strange and not the usual thing is a demon or a work of a demon, seriously. So If there's anyone out there who have knowledge about familiars and they really are and better yet that they actually have they're own familiar and that they can or have been proven or claimed that it is really a familiar.
