I have a dream

I usually make strange dreams at night. I didn't plan about content of dream before sleep, but somehow the contents usually have something to do with my real life in some ways. These are some of them: 1. Doing resesarch work in my ex-lab (forgot its content) 2. I was on a fisherman's boat with its owner (he is one of the fishermans work at our harbour when I was serving as a CGA member. I've forgotten his name though). I wasn't a CGA member in that dream but just sitting on the boat and the fisherman was sailing his boat on a river - like Yellow River in China. As I was sitting at the edge of the boat, the edge crashed suddenly and needless to say I fell down into the water as well. Fortunately the water was not deep. 3. This one could be one of strangest dreams. It was in a barrak somewhere and there were a row of soldiers standing in front of me - their chief. I saw I was blaming at one of them. I couldn't see his face but I can still remember his voice. I: ~!@#$%^&*(!!! He: You can't talk me like this! @#$%^&*... I: Fxxx!! I've been standing you for long time but you still ~!@#$%^&*(^$...!!! I saw this dream just after I entered CGA but hadn't met those guys standing in front of me and didn't concern about it too much; and amazingly they eventually were in my barrack months later. When one of the guys came to my barrack, I had a feeling this was not the first time to see him but actually we never see each other before and I couldn't figure out why I had that feeling that time. ...and one day the situation came to true - almost the same. I was almost going to blame at that guy, and at the same time this dream came up to my mind and realized - it's him!! No wonder I felt I'd seen him before we exactly meet each other!! (Wow! I'm a fortune teller!!) 4. I've forgotten the detail of another one, but I can still remember Peter (my honoured boss) was also in that dream as well!! ...and last night Yuki showed up in my dream. I was gonna leave somewhere (?! a bit similar to my real situation) and somehow he knew one of my secret - a true secret in the real world that I've been keeping from him! Dream is really amazing. Anybody can explain these phenomena?
