I was wondering what this dream meant and why I have been having it every so often since i was a young child.

The dream started out with me by myself in the parking lot, i then saw a headless couple in a rollarcoaster cart driving up to the store. I proceeded to walk in to the grocery store and soon got the erie feeing that i was not alone. the grocery store looked very odd too; it was filled with only the freezers that held frozen dinners. I then met my dad up at the help desk, he was complaining about how the vampires had taken my older sister and ripped her head off(once the vampires got you they would eat your head and steal your skin to wear, but you would still be alive). My dad and i continued to walk around the grocery store and some how ened up in the back offices. After every office we went to the person in the office would be taken by the vampires. We were then forced to leave the store and go out into the parking lot; we had decided that we need to drive to the grocery store on the other side of the country(there were only two grocery stores). When we got to the parking lot i told my dad "check in the back seat first i don't want any vampires to come." When we got to the car vampires were everywhere. They were all wearing the same things; a long light navy blue trench coat and a black bowl hat. the secondd that they came out from under the cars though, their close vanished and they had leopard print skin and ganged up on my dad and me. I kept yelling "VAMPIRE! VAMPIRE!" at the top of my lungs but no one could hear me. My dad and i fought off the vampires we kept hitting them on the head with the hard part of a broom stick.

this is where i woke up and i have had this dream only two other times, the first was when i was around five but we never made it to the parking lot and i was with my sister. the other time i had this dream i was around 11 years old, i am now 15.

CAN SOMEONE PLEASE HELP ME FIGURE OUT WHAT THIS DREAM MEANS!!!! THANK YOU!!!
