I just remembered something particularly strange that happened to me a few nights back. Honestly, it was weird.
So I was lying in bed, very tired, at around midnight. I had not been lying there long, when all of a sudden, what I can only describe as a bright flash, zoomed passed... inside my head! Haha, I know I sound insane, but something whizzed past the back section of my brain. I heard it as well. I'm thinking perhaps it was just a bunch of nerves firing, like a thought "going-off" and because I was kindof dazed and sleepy, it awoke me.
Either that... or maybe... I don't know. Strange. That's all I can say.
