My sister tried to kill me!??

Date: 1/29/2017

I am in my room sleeping , i get woken up to my sister (12 years older) threatening to kill me. She has a knife in her hand and a wicked smile on her face and saying awful stuff to my face. She had the knife so close it was poking my belly. My heart fell to my stomach the fear felt so real. After that i stall to kind of find a way out so i tell her can i at least eat something first before you kill me? She says fine. So then i go to my parents room where they were sleeping then i go to grab some candy next to my mom and i manage to scream and wake my mom up and thats when the dream ends.
