My Grandma came back to live - again.

Date: 4/14/2018

I had a nightmare about my grandma coming back to live.She died 2 months ago. So i had this dream about 4 times now. My Family was in her house and suddenly the door opens and she comes in.Everytime she looks a little bit more like a dead person,like a zombie with big dark eye circles and ripped,used clothing.For the first time,when she looked like she always did,i just said " Grandma?" and everyone else just wasn't shooked.I try to explain that she was dead but nobody believes me and they all act like she was never dead.And everytime i dream it,i always get a little more scared and this time i screamed really really loud 'No!!!' and i woke up. What does that all mean?
