This past Thanksgiving, I went with my family to stay over at my aunt and uncle's home in Connecticut (we live in Massachusetts). I stayed in my uncle's study, where I slept on the floor in a sleeping bag. My uncle loves to collect various objects from all over, some of which are very old. Many of his more intriguing objects can be found in the study where I was sleeping.
The first night was relatively uneventful. I woke up once, but did not check the clock. Waking up in the night is not unusual for me, so I paid it no mind. I was slightly anxious when I was lying awake in there, which was unusual, but I just figured I was being unreasonable.
The second night, though, was when things got interesting. I woke up in the night, and found myself more awake than usual for when I wake up in the night. This time I checked the time on my phone. I assumed, since I felt so awake, that it was maybe 5:30 or even 6:00, as it can stay dark in that room until as late as 7:00. To my surprise, the time was 2:58 am. A few moments later, bright white flashes became visible on the ceiling. They were very large, and were in almost star like formations. They seemed like they would have a centre orb of light, but I did not see their centres, since I was too afraid to look at them head-on. Just then, a very clear female voice spoke, almost from the back of my head. She said "Good thing you're too tired to realize what this really is." I then felt a bolt of primeval fear and a sense that something supernatural was going on. I thought I may have sleep paralysis (I was very awake and thinking clearly, but I was scared) but I found myself able to move normally. I then shut my eyes but could feel that the flashes were still happening.
The next morning, I searched the room for an electronic device that would flash like that. I found none. I then asked my uncle if there was anything that could do that, and he said no.
What did I see?
It lasted from about 3:00 am and I think it was still going on when I was able to fall back asleep, around 3:30 am.
