A dim, dark space. But not too dark. It could even be called a dimly lit space. I was still a kid, and there were many, many other kids like me in this space.
We were all made to do the same things. It was repetitive and boring, and they made us keep doing the same work till our consciousness started to fade. To us children, "life" was just the repetition of small simple tasks. To the point of exhaustion. Even beyond that.
We had no idea that there was a whole world outside of that dark, dim space. I couldn't believe it. The world was actually huge and sprawling. That thought never even crossed our minds.
One day, things changed. The days of performing the same tasks suddenly ended. Then, one at a time, we were taken to a small, clean room, where we met a demon. I knew nothing about gods and demons then, but there was something black and huge and terrifying, and all of a sudden it was right before my eyes. He was inside my head. After tens of thousands of long, sharp needles were inserted into my half-wakened head by these adults wearing white clothes, the demon inside my head howled.
The strange howl that only I could hear echoed horribly inside my head. It kept going. For hours, days, even months.
It went on for years.
