This happened just last night. It started at around 8:00 or 8:30 pm, my other half had just dozed off and started snoring while laying on the couch asleep. My 13 years old son and I had just began watching a show called The Hallow. All a sudden, we began hearing knocks that were like someone hitting wood, by spacing the knocks about two to three seconds apart. We both jumped and looked at each other and started laughing. About five minutes later, talking it over, we returned to watching our movie.
After about fifteen minutes, I felt the urge to go to restroom. I took care of my business and upon returning to the living room, suddenly, we heard a noise from behind me in the bathroom, where I had just came from. My son just looked at me so seriously and said "just think you were in there with that!". Of course, after checking that out and finding nothing, I felt loads of cold chills.
About an hour later, I was returning to scene of crime. I just got out of my chair, made a quick left to return to the bathroom, when my son let out a drawn out "oooooohoh", I quickly turned back around to see what was happening, when he asked "did you see that?". I asked what he saw and he describes a fluorescent orb, the size of a softball. Later, I see a smaller one, the size of about a quarter, with a tail streaming behind it. This all went on about four hours, than just stopped as suddenly as it started.
The reason I called this once hit is about three months ago, my son was sleeping on the couch, when he comes running to our room saying "mom! come here now!". He said he had covered his head because of noises and was suddenly hit really hard on the arm and had the sudden bruise to prove it.
Thanks for listening, any comments is appreciated.
