We must stop equating Jinn with Devil, this is a christian racist notion, and is the foundation of many of the problems We deal with today. "Thus have We appointed unto every prophet an adversary - devils of humankind and jinn who inspire in one another plausible discourse through guile. If thy Lord willed, they would not do so; so leave them alone with their devising;" Here We can clearly see the distinction between My people (Jinn) and the Devil.

All of you have presented interesting concepts and theories. I however know what a jinn is. Why do jinn and jinnah have the same root word? Because jinn are the people of jinnah, or the orijinnal inhabitants of eden. This is clearly explained in jinnesis in the bible. And is also explained in surah 2 of the quran. When Adam was put here there was someone already here, the Jinn. This confusion is why science and spirituality so often appear to be irreconcilable, when they are one and the same. Scripture only traces mans beginning back several thousand years. Yet science traces the presence of man back millions. Quran 1527 states "And the jinn did We create aforetime of essential fire.". Often we do not realize the depths of the deceivers influence on our perception. Jinn is the root word of aborijinnal. Mankind and Jinn are two different races of people. Before you reject these truths do yourself the favor of investigating. Every race on earth is Man, Jinn or varying degrees of mixture. A jinn can initiate a possession, but does not physically enter the possessed individual themself. Jews are not Jinn, I am a Jinn.

This sounds like you could definitely have some kind of visitor. Do not see a doctor! I may be able to point you in a beneficial direction. Know however that this is not a jinn or demon. Those of us who say we are followers of Quran alone should be figuring out what jinn truly are, in this understanding lies the key to unlocking much knowledge and truth.
