I can be in a deep state of sleep and control dreams to, it is nice, I can talk to the girl I like and see what she responds like, and gauge what inside my mind really feels about her.

Yeh, I control my dreams a lot. If I don't like how the story is developing, I just correct things to suit myself. If there is a mistake in the dream, I correct it. I change people's identities frequently. Like if I am talking to, about or doing something with someone that doesn't fit right, I switch the personage to somebody else. Most of my dreams are in the morning as I am trying to wake up. They are very realistic. All my senses seem to be intact. The one thing that is really fun is when I fly. In my dreams I can fly like a bird and see everything from a bird's perspective. It is really neat. I can say I have never had what you call a nightmare. When things start getting unpleasant, I just change the situation to something pleasant. Sometimes when I am trying to wake up, I have frustrating dreams. In them I am trying to accomplish a simple task that is escaping me. It becomes so maddening that I wake up just to stop the excercise in futility.

I think I do that almost every night. It is like making up a story, like I sometimes do during my day. Like a daydream, just that it is at night. If I have a crush on somebody, that maybe I will dream about them. It is often that, not so often I dream about other things... And when I do, I do not feel like I created those dreams myself.^^

I think it is fun. I like dreaming about things that are interesting for me, than dreaming about some stupid cat outside or something like that....

What you people are describing is called 'lucid dreaming'. Here's an excerpt from wikipedia:

I find when I sleep a full rest of 8 or 10 hours, I tend to lucid dream more. The longer I try to sleep, the more lucid my dreams become. Most of my lucid dreams are re-ocurring dreams.
I dream about running from authorities and succeeding by doing everything possible, like stealing helicopters, etc. It's a whole lot of fun running around in my dream from the police.
Another dream, I'm usually in the middle of a war against a non-humanoid threat or on some James Bond type of mission, escaping from a facility. The non-humanoid dream, though, isn't a pretty one... the threat is vicious and I'm usually armed with an assault rifle or gun. The human race does not win very often in this dream. The last dream I had like this, mankind had run out of all ammo and I was frantically searching for even a few bullets.
I really, really, REALLY hate lucid dreaming about my place of employment.

Whatever lucid dream I have, I've awoken with that ghost feeling that I really was somewhere else. If I get shot and I wake up, I hurt where I got shot and many other sensations linger after dreaming. This leads me to believe something on the spiritual level happens when I lucid dream. I think that a spiritual part of me, my soul or whatever, goes to another realm and takes part in life in that realm.

Anyone else feel these ghost feelings? Ever realize you're lucid dreaming and can't do anything to wake yourself up?

I like flying or being underwater in dreams, but I never seem to actually fly, I merely float up and float back down. It's always frustrating trying to fly in my dreams.
