nightmare

My cousins from another state sent my family a hyena to keep for a couple of weeks.
What for, I don't know or remember.
At first it was very playful like a dog, we would play with it and things like that.
But when it came to feeding, it starting getting very aggressive and wanted to eat us.
I don't remember much but i remembered it bit my arm and my arm was bleeding.
It started coming towards me like it was going to attack me.
Then i just woke up.
