Possible shared dream?

One night, I was dreaming, experimenting with dream control tactics I've learned form several sites. Well, in this dream I was sort of controlled, but fragile hold at best. I was in this apartment, talking with this girl I've never met before. She had flaming red hair that fell just below her shoulders, a slender figure, stood about 5'6", probably weighed about 113 lbs, she looked 19, wore a horizontal striped red and white long sleeved turtleneck with brown khaki pants and green socks over her feet.

We mostly talked about eachother during the dream, I was explaining how I was experminenting with some techniques. She asked me what for? Then I told her, well you see, I'm dreaming right now, and I want to keep myself asleep.

Suddenly I felt the dream lifting so I began the dream spin technique. When I restablished my hold on the dream, she looked at me with her head tilted. "Why do you want to stay asleep?" she asked me, and I replied, well, if I wake up, I'll never be able to see you again." then she said "awww that's cute." then I woke up.

Throughout the dream, it was difficult to remain calm simply because being near that girl just seemed to lift all my worries away, her presence was comforting, made my heart nearly burst form my chest. When I woke, I was sorely depressed that entire day.

What do you suppose it could mean? I have a feeling it goes deeper than just some heartfelt desire/wish.

Alright so I don't know how to change the title or edit my first post, so I think I'll use this thread to post each dream that I'd like help or thoughts on interpretation. So here's the next dream.

I'm in my house, carrying a box of marbles down my back staircase. When I reached the kitchen I heard whispering coming from the house, and I immediately set the box on the floor in the corner of the kitchen, and dropped low to the ground. I looked around and let myself out of views of any windows nearby, couch blocking me form one window, and the kitchen island blocking me from the windowed door leading to out backyard. My heart began to race as I couldn't see anyone, but every now and then heard that whisper. slowly I crept to the front window, and looked out towards my driveway, where I saw my car. I turned, opened the door, and ran out to my car, but as I stepped outside I suddenly saw a white truck parked backwards behind me, and a green car parked in front of the truck. I opened the driver's door to the truck, and it was my dad, he just looked at me without interest. Then I crouched, and crept towards the green car. There were 2 people inside of the car, so I crept towards the passenger side door first. I opened the door, and there was a man, I couldn't describe him very well, for some reason he was of no concern to me, just an obstacle as I crawled into the car towards the driver. The driver was a girl, very beautiful, long black hair, rose red lips, sparkling green eyes. For some reason when I looked at her I thought, "She's a quintuplet" I pushed myself next to her and sat down. she grinned at me, and I immediately felt calm, even a bit entranced by her. Then I woke up.
