When he opened his eyes, he saw a dark being sitting on him, choking him. When he tried to move, he realized that he was paralyzed. In his mind, he envisioned a cross, and immediately, the being vanished, leaving the man gasping for breath. He also does not fully believe that he had an evil visitor in the night."My mum encounter this thing a couple of times, at 1st I thought its just a bad dream...but when I read bout it in a newspaper article, I did a search on the net n found the site above. What is strange is, she describe evrything exactly like the 1 above...a few days later, 3 readers wrote in to that newspaper telling about having the same experience. I would like to hear what u have to say about this!!
