A dream, Freaks me out.

The dream was short, but did enough to wake me up and scare me. I was dreaming about the girl again(http://www.dreamviews.com/forum/viewtopic.php?t=34207), or should I say, my best friend. Once in real life, I told her that I loved her like a sister, and now I wonder if that was a mistake, because I have other feelings for her than that. Anyway, to the dream...
The dream starts, and I'm in a room with colorful pictures, and some famous artwork, like the Mona Lisa, the Scream, and I think the Potato Eaters. In the middle of the room I stand, and then this girl, Katey, appears in front of me. She's just standing there, with no emotion, and I walk up to her, and tell her that I love her. She looks up at me, and smiles, then two seconds later, the color starts to fade the room, the scream actually starts screaming, the mona lisa starts to frown, and the potato eaters just fall out of the picture as regular potatoes. and the I look at Katey, and she's crying, then, everything turns black and white, and there's no sound at all, and I start to take a step back from her, but as I step back, she steps forward, and I can't take her crying, I hate to see anyone cry, especially women. Anyway, I keep walking back, and I trip, and almost instantly shes right over me, just staring at me, and I say, "I didn't mean to make you cry", and then I woke up....

If ever I wanted, but didn't want to wake up from a dream, this would have been the time, so please, can you help me?
