Dream Of Injured Guinea Pig Party

I was with several other people i knew in the dream and i was looking for my room or something in the dark. We were going down different halls and it was all dark but in every corner there was a black long flashlight or two that was for people's use. I got one for a moment and it worked and the light came on but i figuered i didnt need it so i didn't use it. I was looking for a bathroom and the others werent. I remember then being at my family's house and there was a party. I had 5 pet guinea pigs in my dream that i kept outside in two cages. I looked and counted 6, so i knew one had to have been a stray who came in. I looked in one cage and it had three and they were all healthy, so i fed them. Then i looked at the cage on the right on the ground and my favorite guinea pig was on his back and looked like he got injured. I carefully picked him up and he had some of his head cut out on his left side once i saw how injured he was and i cried believing he must have gotten into a fight with another guinea pig and I'll have to seperate him but wondering if i should take him to vet or euthanize him in case the pain is so bad. Initially ut looked like just his eye and nose was injured but when i saw some of his brain i thought i better let him die as comfortably as possible. I was very sad in the dream at this point.
