Jinn possession is common in Islam and you might compare it to voodoo or satanic possession. The devil is always represented as a snake. The size of the snake depends on the strength and age of the devil. This type of possession takes a specialist. If you have one devil or jinn inside of you or in your home then trying to kill the snake will bring 100 more. So ridding yourself of this takes a specialist. Look at this: If you try to kill me, I will bring my friends to hurt you more. The snake may leave you temporarily to get you to stop, but as soon as you get laxed, he returns. If you are truly possessed you will see more problems after 3am or early in the morning hours.
