Granny Vampire Nightmare

When I was a kid I had a nightmare about a vampire. I woke up went to the kitchen table to eat breakfast, after I was going to my room then out of nowhere I see this old lady unpacking her stuff. I asked her who she was and what she was doing in my room? She began to hiss her eyes turned red and her teeth became sharp, I started backing away slowly turned around looking for my Mom asking for help. Then my Mom came at me looking exactly like the old lady I was cornered by both of them terrified, before they could attack I woke up.
