Over the past few years I haven't experienced anything other than the usual knocking sounds and shadows... Fairly normal stuff here that I've gotten used to. However, the other night I got up at around 2 am to use the bathroom and had an unusual experience that I wanted to share.
I walked out of my bedroom into the hallway to get to the bathroom which is across the hall and down about five paces. If you were to continue down the hall past the bathroom you would reach a doorway to the living room on the left, whereas the kitchen entrance is at the hall end on the right.
The hall was pitch black in darkness. I don't usually turn lights on because I know the short distance to the bathroom and don't think about it. As I was about to turn into the bathroom I heard a deep male voice coming from the living room. He sounded as if he was facing me, and his voice was clear and projected to me well. He said "We're almost done here." I got the impression that he was with some other people and they were working on something in my living room. I didn't see any signs of light, so I didn't feel worried about an intruder. I also didn't think an intruder would make that announcement.
In the bathroom I quickly closed the door and turned on the light. I thought perhaps I had imagined the voice and that maybe I was still a bit asleep. So I did what I came to do, and turned out the light before opening the door to go back to my room, and didn't worry about it.
When I got in the dark hall, I heard the voice again, saying the same thing. I quickly went into my room, locked the door, and slept the rest of the night with a dim bedside light on. I file this away with the strange and unexplained experiences.
