My New Grave

My grandma died about a month ago.. Sometimes I go to her grave and morn. And I decided to do the same today.
I got in my car and started to head to the graveyard down EastWood, the traffic was incredibly bad and slow, but I got there fairly early.

I got out of my car and walked to the gates, something felt off, something was watching me. I felt a sudden urge not to go in but, what could happen anyways, I always got here and nothing ever happens...
I opened the gates, then walked in. Shivering wind blew down at me from above, good thing I was wearing a jacket! The sensation of feeling watched, followed, stalked, hadn't left though...
"I wonder if it's a spirt or... Maybe grandma!" I thought to myself trying to make things better. Once I got to her grave, I sat down next to it and patted the muddy soil where she lay. Just then my ears started ringing and my head felt light..
"What was going on?!" I mumbled, putting my hand to my forehead.
I looked up and saw my grandmother standing next to me.. She wore a long silk dress covered in dirt and stains, and a small blue bracelet, the exact same clothing she had before she passed.. Her jawbone turned up and down like she was trying to communicate, but each time she did, my ears rang louder... And louder...
I covered my ears with my hands, then looked over to a 6ft hole, and a wide open casket... I looked back over to her jaw moving quicker and quicker, till it creaked and cracked. And fell to the floor...
I gasped and fell backwards, landing right in the casket as it closed shut. I pushed and knocked on it but it was no use... It was as if the coffin door and the casket was cemented shut. I screamed for help. But no one came..

Soon my ears stopped ringing after I gave up. And I heard dirt pile up on top of my new grave.
