I'll try to keep the dream short.
I was at school. We had to work on a project. I ended up alone in a room with a computer or two. I was just chilling out a bit when I looked over to the window. There was a boy standing in the room. He was about 10 years old and had brown hair. I competely flipped. I was thinking: "wtf, I'm hallucinating." The whole scene started to morph. It's was like how you show the viewers of tv that someone is high on drugs. The boy was pretty clear though. I reached out for him with my right arm, and as if he was a reflection in a mirror, he did the exact same thing. The whole moment was so intense.
I think I didn't wake up after that, but ended up in another short scene. I hope I'll see this DC more often.

So what's up with this? I mean, I've had weirder stuff happen than this, in dreams. Why did I react so strangely? I figured I could've been on the edge of going lucid, but as I said, I didn't wake up.
Does anyone have experienced something similar or does someone have a possible explanation?
