That's interesting you say that CuteCandy, i'm curious as to what makes you so confident about that, like where did you learn that from? Because I have often thought the exact same thing.
Many times I've had dreams about people, usually females, that I feel I've made real connections to in my dreams. There are two girls in particular that I'll dream about from time to time and I look forward to everyone, these dreams are usually the type of dreams people call lucid dreams, where everything feels really real to you. After talking and hanging out with them in my dreams, upon awakening, I always have the feeling that it was a real meeting, that somehow we actually met and were interacting with one another in our dreams.
My theory was always that maybe most of the time our dreams are just random creations we alone make, but that every once and a while two people will some how meet or come together for a time while asleep and interact and share a dream with one another. In one instance I remember dreaming about walking into some high rise building......while I was entering one of the doors a friend I knew in high school was coming out of the door right beside it, we both got half way past each other and then at the same time got excited and turned to greet each other when we recognized the other person, we said hi and had a half shake half high five and began asking each other how we'd been and what we were up to. I've always thought and wondered if maybe we really met in the dream world. And like I said, along with that instance, I'm always having dreams about females that make me feel I really met them in my dreams, two girls in particular, and the thing that really makes me think it was a real meeting/s (other guys would probably understand this) was that the dreams were never really sexual like most dreams I normally would have about women, in these dreams I always had a strong feeling of genuine love, like we were best friends and I'd do anything for them. I loved them in the man and woman lets get together and make babies kind of way too in my own mind while dreaming, but that never manifested in a physical sexual way in the dreams it was always the feelings of genuine love, interest, and caring for the girl........I can't really explain how those dreams feel when I have them, but I always feel like I may have really been with them and them with me in these dreams.
