Thousands of people have sighted strange looking creatures all over the world. These sightings however, have still not proven substantially that aliens exist. Rather - and it seems more plausible all the sightings of such creatures were just Jinns parading in different forms. The ability to possess and take over the minds and bodies of other creatures is also a power which the Jinn have utilised greatly over the centuries. This however, is something which has been prohibited to them as it is a great oppression to possess another being.
Human possession is something which has always brought about great attention.
But the true knowledge of this subject is rare amongst the people. Over the last 3 decades the subject of possession has become very commercialised. During the 70's films such as The Exorcist and Rosemary's Baby were used to educate people about possession. We know as Muslims, that Jinns possess people for many reasons. Sometimes it is because the Jinn or its family has been hurt accidentally.
