Was She A Dream or Ghost?

Last night I had one of the strangest dreams I've ever had in my life.
You know how some dreams make no sense at all, some seem very real, some are "dreamlike" and yet others become Deja Vu? Well I hope this one was as premonition because it was the most "real" dream I've experienced, hence the reason I decided to share it here with my friends.
I found myself standing in a field of tall green grass facing a small hill. As I started foreward, I could feel the wind blowing the grass against me. Looking up I saw black storm clouds moving toward me, so I took off running towards the hill leaning foreward and pushing as hard as I could up the hill with my toes.
Approaching the summit, I felt cold rain on the back of my neck as I raised up to see an old barn. Not your typical red barn with "pointy" roof, but a greyed cedar plank shack with a tin roof.
As I hurried to the only door I could see, I noticed it was merely nailed together boards held shut with a rusty chain and bent nail. Unhooking the chain, I lept inside as lightning crashed outside.
Catching my breath and looking around, I noticed there were wooden pens and hay everywhere. Turning around, I leaned against the facing of the open door, letting a little rain drip on my head and face.
As I looked up, I saw a face in front of me and jumped back, wiping the rain from my eyes.
She smiled before shaking the rain from her raven black hair ; her curls falling gracefully upon her breasts which were covered by a rain soaked T-shirt.
She pushes me from the doorway and against a roof beam in the middle of the dirt floor. She stares at my chest for some reason before biting her lip. Suddenly her hot breath is on my neck as her lips kiss it lightly. I turn my face to hers as she pulls away to meet my eyes.
BEEP_BEEP_BEEP_BEEP..........F*ckin' alarm clock!
Attempts to return to sleep and finish the dream are in vain. I'm just too used to getting up.
I truly believe this was no "fluke" how the dream ended. Was she a ghost, a siren, a demon, or what I'm hoping for-the shape of things to come.........
