+18 never had sex but in my dream i felt it

In this dream, I was back at my old primary school and there was this game where a group of people had a gun and then the rest had to hide and try not to get killed before the school bell rang.

I was chosen to hide so thats what I did, I hid in a bush near the swimming pool and then there was this guy who had a gun who saw me running by the pool (he had blonde hair).

I hid under a big bush that was near the swimming pool and he came looking for me. I saw him staring into the bush ready to shoot but then I shouted "please dont kill me ill do whatever you want me to do!" So he put his gun down and told me to run into the swimming pools changing room. And thats what I did.

He followed me into the changing room and there was another guy in there but I cant remember how he got in there but he was also part of the group who had guns. Anyways the blonde guy who found me took his shirt off and stood in-front of the other guy and they both looked at me. And then I stood really close in front of them and I started touching them.

During that moment I actually felt it. I felt a bit of pain but also it felt good and I thought It was real.

Is this normal, and how does this happen?
