Crying Blood?

I had a dream last night that I can't stop thinking about. I was in a room with two people. One of them was smaller than me and was crying blood, and I had my arms around them trying to protect them. There was another person much taller than me who was also crying blood.

I was trying to protect the smaller person from the bigger person. The bigger person was moving at us slowly, kinda shuffling, and the more me and the smaller person tried to step further back into the room, the bigger person would approach us faster until it got to us and then I woke up gasping and covered in sweat.

During the dream, I didn't get the sense that the bigger person wanted to hurt me, but the smaller person I was protecting. I was scared of it hurting the smaller person.

Also, as the bigger person got closer, they both slowly shifted into like, a rotten monster version of themself.

Any Idea what this could mean?
