Strange Childhood Dream...Previous Matrix Life?

I had a strange when I was a child or early teenager.

As I was sleeping it was like a awoke in a cage of sorts. It was a large cubic shaped caged like mechanism that housed hundreds or thousands of people. I remembered that I was laying on top of a woman...a naked woman. I was naked too and was a male in the dream as in real life. Each cage consisted of a couple in their own rectangular cage as if locked in together in the traditional mating way.

I remember thinking "What? Where am I?" and lifted up my head. It was as if I had awaken in the dream to a strange place. I remember seeing a great fire away from the cage, where great sounds were coming from. I remember the people in the cage sweating and mating. I could see them through the gigantic cubic cage which seemed to be made out of a soft wood, like logs. It was if we were built to be machines to produce seed. I remember not feeling scared or startled that I was in a giant mating cage for it felt good, obviously and I was comfortable. But it was if I knew what being free was like in the dream (for I was conscious) and I started to feel trapped in this giant machine. I then went back to mating and went back unconscious and woke up later.

Could this have been a previous memory from a previous type of existence? The incredible detail I had in the dream couldn't have come from the mind of a child. I have never shared this strange dream with anyone until now.
