Anyone have any idea of what this means?

okay wel i had this dream my best friend and i are in the mall she's in a wheel chair but she can walk and she was sitting in the wheel chair and i fling a rubber band and it cuts under her skin and i get up closer to her and it is bleeding very bad she lifts up a flap of skin and pulls out the bloody rubber band. and i wanna call my mom but my friend won't let me she doesn't wanna go to the hospital or anything. so we just go looking around and i have my phone but it doesn't work too well. then i go outside and see one of my used to be friends and i walk and call my cell phone from another phone and my used to be friend was listening to me and was concerned when i was talking about the injury. then i go into a different dream where we dig up eith my Great grandmas or my aunt vernas grave my aunt verna died like a week ago and my grandma died in 79' by the way. adn anyway my mom and brother dug her up and had like a beauty mask on her and she was in a stroller then they took it off and i got a little glimpse of her face and it seemed scary to me so i ran off to our car and then i woke up.

any ideas as to what this means i need all the help i can get ask all the questions you need to it will help more if u ask and get more explanations
