Need help interpeting a dream!

Hi everyone! I hope someone can help me with this. I have been going through an upheaval of my life and I can't figure out this dream. I'll be as detailed as I can.

It starts out with myself standing next to a large body of water. Next thing I know I am walking along side a lost love of mine. Some one I hold dear to my heart even after 11 years. We are in a public place It seems to be a breakwall we are walking along perhaps a dam. Next thing I know we smile at each other and jump in the water. We sink to the bottom of the water about 20 feet down. At this point I felt overwelmed with hapiness. Then I here someone call my name. I look to see a friend of mine and he yells your standing in a nest! I look around to see alligator skelitons laying all around us undesturbed as if in a museum. The water is almost clear like in a public swimming pool. Very blue yet a little cloudy. I look back to my freind as he pulls himself out of the water. Now I feel dred and panic. I lay down on the sandy bottom and pull my lost love close and roll on top of her to protect here. I look again to survey the situation and the skelitons are gone but a single live alligator has taken there place. I tell my love to stay put. watching the gator I swim to the surface and pull my self out. The gator didn't move so I splashed the surface and waved under the water so she would follow. I could not see her because the water was bright from the sun above. Eventualy her hand came out and I pulled her ashore. Next thing I know I am walking down a concrete staircase out onto a city street with my freind at my side. My love is standing on the sidewalk dancing and smiling at me. I focus on her smiling face untill I suddenly see someone standing next to her, another female I don't know. I felt very happy to see her dance but dissapointed when the other girl appeared.

I can't figure this one out. it is so vivid and it sticks in my mind so clearly. I know it's important! I am overwelmed by it! Any help would be appriciated
