Trickery.

One night, two or three years ago, Jan, 4.
I was just about sleeping, I was having a peaceful dream, until a random beast came out of nowhere and started fighting me, I heard realistic laughing and while I was fighting, I heard my Dad scream at me, "WAKE UP [redacted] YOU ARE HURTING HIM!" I woke up, just to see I wasn't fighting a beast, I was fighting my little brother, who was bleeding from his nose and lips while I had many many bruises and scratches.

It turns out my little brother was trying to beat me up while I was sleeping, but my aggression fought back and I accidentally hit my cat, Tina, so the cat started scratching me and trying to harm me as well.
