The line between dreams and reality

The dreams I wanna talk about today aren't people's wishes. What I'm referring to in the title are the dreams that occur while we're asleep. There's still a lot unknown about them, and to me they're one of the most fascinating and mysterious phenomena linked with the human mind. Throughout my life I've had some really weird experiences linked with them. Most of them occurred when I was younger, so nowadays I don't remember much anymore. I did however experience one of those weird moments just some hours ago, so I thought I would share the experience with you. It was basically a short term premonition. Since I do not live alone, it is not uncommon for my flatmates to wake me up in the morning because they talk too loud. After being woken I decided I'd try to go back to sleep as I was still tired. I couldn't manage to enter the deep sleep state I was into earlier though, because they kept making noises. Eventually, I got into a dreaming state in which the setting was identical to my flat. In this dream both my flatmates and I were in the kitchen. I am 100% sure I was dreaming in that moment because rather than walking I was floating in the air. One of my flatmates was studying on the kitchen's table and the other one passed right next to her. In doing so, he accidentally hit a glass with water in it, spilling some on the book she was reading. At that point, I woke up. Some minutes later I walked to the kitchen in order to have breakfast when the very same scene I had witnessed took place: the guy hit a glass of water spilling some on the book the girl was reading. Some of the details were slightly different, but I was still left speechless. What do you think?
