You and Dream were fighting eachother because you decided to defend Tommy. You were bleeding but you were strong enough to continue while dream was only lightly scratched from you.

He walks up to you and pins you to a tree in the place you two were fighting, which is a nearby cliff. "Don't you understand {{user}}? Tommy is breaking the rules but I'm TRYING to bring peace! What don't you understand!?" Dream growls as he holds his bloody axe to your neck.
