This story actually happened to my dad, not to me (I wasn't even born yet).
My dad's first wife wanted to divorce him, but my dad did not want the divorce. In court, he stated that the Bible says a married couple should not get divorced, but the court granted the divorce anyway. Shortly after the divorce, he moved out of their house into a small trailer. One night while sleeping, he woke up and felt an evil presence, but did not see anything. As hard as it was to go back to sleep, he pulled the covers over his head, shut his eyes, and finally went back to sleep. The next night he woke up to see a green haze had permeated his room/trailer.
He knew it was an evil presence of some kind, but did not know what to do, so he pulled the covers over his head and eventually went back to sleep. The next night he woke up in the middle of the night and saw what looked like an electrical storm right there in the middle of the room. Small lightning bolts were striking, and he said he felt electricity surging through the back of his neck, and he also felt what he described as "two orbs revolving around each other" in the back of his neck.
Once again, he pulled the covers over his head and eventually went to sleep. The next night he woke up in the middle of the night to see Satan himself standing at the foot of his bed. My dad said that he did not announce himself to be Satan, but he knew in his heart that it was Satan, not just a demon or a ghost. He did not look like the typical Satan that you see with horns, tail and a pitch fork. My dad said he was a very attractive man with his hair slicked back, very clean cut looking and wearing a suit.
Then Satan spoke. He said, "God will do everything in His power to destroy you." and with that, my dad had had enough. He said, "Devil, I command you to get out of here in the name of Jesus." and then Satan disappeared. He didn't leave a poof of smoke or anything when he disappeared, he just disappeared. He said at that point there was no more evil presence in the room, and he did not feel fear anymore at all, but rather an overwhelming sense of peace and security.
That was the first and last time he saw the Devil himself, but years later after he re-married, he was lying in bed at night with his new wife (my mom), and he once again felt an evil presence. He said he could not see anything, but he felt and heard a deep growling sound, much like a large dog would sound, and that it was coming from his chest, as if something were sitting on top of his chest. Once again he said, "Evil spirit, I command you to leave in the name of Jesus." The growling stopped, and suddenly the closet door shut itself. My dad then said, "And I command you to get out of the closet in the name of Jesus" and then the closet door opened back up, and he said once again he felt an overwhelming sense of peace and security.
