So today some friends in my apartment building claimed they had some supernatural things happening in their apartment. They said that a fowl smell orginated and as that smell became apparent their tv had the juice sucked out while the rest of the electronics remained on. When I went up for inspection all seemed well.Then my friend came and sat down on the arm of the couch and fell into a trance he became unresponsive and fell off the arm of the couch to floor. He stil remained unresponsive and his eyes rolled the back of his head. He was still breathing but not that strong and his heart rate increased at a very rapid pace. When he came to, approx two minutes later he recalled someone openning the door and an unknown figure entering the apartment and putting a blanket over him, causing him to "black out". Please excuse my supernatural reasoning, I was wondering if their was any medical explanation for this behavior?
