Weird assed dream

I just can't seem to get it out of my head and it plays over and over again, it really is quite baffling.
I'm standing in a hospital, waiting at the reception for somebody to come and attend to me and the place is eerily empty save for the odd nurse that walks through the waiting room and through some large grey double doors.
Suddenly the lights above my head begin to flicker and in that split second the room is in blackness, the black shadowy figure of a girl I know all too well as someone who has haunted a previous recurring nightmare, and several others is visable and vanishes the very moment the light comes on.
I know her as the ghost of my unborn daughter Rielle who now only has one month to wait before being born.
I know that all that doesn't make much sense, but this girl who must only be around 5 years of age with long raven black hair has only started appearing in my dreams since I became pregnant.
Anyway, the image of this girl scares the hell out of me so I run and push myself through the double doors into a long corridor, I keep running until I emerge into another waiting room at the other end, and this room is bustling with patients and doctors etc.
I feel safe for the moment, then the lights flicker again and then the power in the hospital dies.
As the emergency generators kick in and the emergency lighting activates, I see the shadowy ghost appear in the half light, I can't see her face but I know she's angry and suddenly papers begin to fly off desks, sparks of blue electricity emit from nowhere, the receptionist is hurled over her station and into the middle of the waiting room and a doctor is thrown into a re-enforced window.
I quickly run behind the reception desk, grabbing the phone as I duck and hide behind it... I lift up the reciever and hold it to my ear, but don't know who to ring and as I am thinking a doctor kneels beside me and tells me something, I can't remember what he said, but instantly, after he did I stood up to face the ghost.
I look at her and she is no longor shadowy, she dusts down a mud covered black dress and looks at me, her skin is pale and as pure as winter snow and her eyes are a dazzling sea blue.
With her long black hair tucked back behind her ears she just stares at me until I hear her say "mummy" and thats it, thats all she says, and only once before picking a teddy bear up off the ground and walks off down the hallway, carrying it like Christopher Robin did with his Pooh bear.
Also, for some odd reason, I can also remember a large green plant in the corner behind the reception desk... I'm not sure as to why that stands out to me, but it does.
