What word mean exaggeration in writhing?

Well, exaggeration means to overstate something that is slightly not true

I’m writing, it means to add a few fictional phrases to a real world thing that happened to you or someone or something

Ex, There was so much blood on the floor that heads were falling off and the hallways were overflowed with a pool full of blood

That’s exaggerating a statement?!

It means that there was a lot of blood on the floor
