I had a dream I was lying down in my bed, and some dark figure was standing at the end of my bed. He had red glowing eyes, and for some reason, he had the voice of a generic New Vegas NPC, constantly saying "I'm watching you." Every once in a while his voice would get really freaky.
I eventually woke up and didn't think it had been a dream at first, and I think I stayed up for an extra 2 hours, making sure he wasn't there.
