A Weird Dream

I've had this dream for many many years now and it seems as though the longer i have it, the more into the dream i go and i really just don't understand what it means.....here we go.  Picture it.....lol  1970 's, nightime and i'm walking up on a road towards the beach between two huge sand dunes, the waves rolling up on the beach so loud that i can barely hear anything but i hear what sounds like a lady crying...so i approach slowely closer to investigate. i am not sared just cautious because i can feel like there is someone watching me but i can't see it's so dark. there's nothing around this beach, no bars, nightclubs, homes...etc just what looks like a road that leads out of town, i can see a road sign but not clear enough to read what it says....it's almost pitch black and the only light out is like a street light thats about to go out and the moonlight. i get closer to the crying and now i'm sure that that's what it is but from who? and why? i'm now off the road and on the beach walking through the sand which is hard because i feel as though i've been walking forever, i stop to catch my breath and i see her. she's lying on the beach in a yellow bathing suit with her shoes lying beside her. shes not moving but still crying and now the closer i get, the harder it is to hear her because of the waves crashing on the beach. i finally get to her only to see that she's dead from having her throat cut almost to the point of a beheading. no movement, no sound now and i stumble backwards almost falling over when i feel someone grab me, i turn around quickly to see that it's her!  i look back on the beach and her body is still there!  i try to scream and can't. i try to run and can't move because the beach sand feels like quicksand. shes talking but i can't hear her and it's not so much a scary site to see her but just a startle because i know it's her ghost. the waves calm, she lets go of me and i hear her say that she needs something but i cant quite understand what? and why me?  shes trying to tell me something and the more she tries, the louder the waves get making it impossible to hear again, my heart starts to race, i can feel something bad coming and she disappears....and i wake up.  last night when i had this dream it sounded like she said that she needed something from me but what i have no idea???   i just can't figure this out and it's a haunting dream to say the least.
