Well it is true that some people seek sorcerers to implement Jinn that are satanic
demons into mankind or his house or his business to finish him or make his life miserable or to stop flow
of his business income... In such case it is either you are religious enough and say your prayers often then it becomes hard for this to harm you or otherwise you need to find some one who practice exorcism to remove this evil... But many are just pretending to be good at it and help you not but squeeze
money out of you with tales and stories... There is another type
of possessions and that is not through a sorcerer but directly by coincidence what man is at his weakest moments and those weakest moments for a possessions are when you come through a great fear or when cry or laugh loudly in hysteria, or during a certain moment
of mating... or even when sneezing loudly... That's why there are prayers to be said on daily basis to guard you from such things and specially if passing haunted places such as deserted houses but most evil ones are residents
of public toilets and market places... Some
of them even would claim that you have made a wrong action by which you have killed a dear one to them and for that they have possessed you and that is mostly night time such as throwing a cigaret butt to a dark place or stepping killing an insect or even an animal at night which could have been one
of them or possessed by one
of them... So this is true thing happening to many who suffer unexplainable illnesses or sufferings which could look like mental illness that comes and goes as pleased...
Many
of the apps are devoted to sweetening those times when you're able to negotiate your way
out of a fight, forcing
demons you recruit to give you gifts or
money and adding the option to persuade
demons you don't want hanging around to bribe you into not killing them.
