Vessels

Vessels
A vessel is a human that has been ocupied whether voluterry or involentary by a supernatural entity in order for that entity to be able to phisically interact in our realm or to move around undetected. Both Demons and Angels require a vessel if they wish to interact with humans; demons espesially considering they are non coporeal withought a host whilst angels need a host for similar reason but also to shield humans from being exposed to there true forms wich can be overwhelming to most humans.

Demons will usually take the host by force, somtimes attacking a potential host withought them being aware of it or sometimes chasing them in order to torment the victim first. Once cornered the Demon will then force itself down a vessel's mouth in the form of Black smoke giving the appearnce that the person is choaking. After that the demon has full control over the vessel and will remain undetected thanks to there abbility to use the vessel'd memories in order to fool friends and family in to thinking everything is fine. However Demons have little or know emotion wich may lead to suspission; forcing a demon to "deal" with anyone who comes to close to diserning the truth. Normally a demon will keep the human personality surppressed or restrained forcing the vessel to watch the atocities they are forced to do. Some humans however; espesially those with a strong will can resist the demon's control and temporarilly regain control of themselves in order to try and warn people of there condidtion.

A demon can be exorsised from a victim with the proper rituall but the prosess is described has very painfull and traumatic and it is not uncomon for the vessal to be killed in the prosess. Ruby's knife has been shown to kill demons but at the expece of killing the host aswell; however in Season 5 it has been shown that if somone is stabbed with the knife in a none leathal area, then the demon can be killed withought killing the vessel.

Angel's on the other hand will only take a willing vessel and will not and can not force themselves in to a human like demons thanks to laws of God. Because of this and the fact that most humans can not stand the sight of an angel's true form the angels have to find willing vessel's. Once finding a potential host the angel will then comunicate with the human through vissions in oreder to explain themselves and ask the for the human's consent in becoming a vessel. Such has when Castiel contacted Jimmy through the electronics and showed him through vission what was to come. However Lucifer tormented his vessal in order to get his consent through psycological hallucinations. Angel vessel's like demons have superhuman abbillities that exceed or even surpass there demonic counter parts. It is unkown whether angels supress there hosts like demons but Jimmy describbed having Castiel inside him like being "strapped to a comet".

Angels can leave the host whenever they want to or if they are called away by the higher ups, leaving the vessel with little or know memmory of the time they where ocupied. The prosess also dosent kill the human either. Also has angels do not need to eat a vessel may find themselves extreamly hungry after being freed from posession.
