I had an interesting dream last night...

I dreamed that I had split personalities and I would talk to myself all the time and see my other personalities. In fact, all of my friends were all in my head and every time I would talk to them I would be playing both people without knowing it. Apparently the other personalities neglected to tell me that we were all one person with different personalities because they all knew. I felt pretty stupid because I thought about all of the times I had sat alone in the hallways at school thinking I was surrounded by a group of good friends when really I was sitting alone talking to myself. I guess those girls that looked at me didn't think I was cute after all... just crazy. This was perhaps one of my most vivid dreams after and quite emotional. The weirdest part was I felt like since all of my friends where part of me, I could look in through their eyes and see all of the things that made up their personalities. I now feel like I know everything about them.

Has anyone had any really weird dreams like this? What have been your most vivid and realistic dreams that you can think of? This one definitely struck home with me... It must have lasted at least an hour and I didn't get over the idea until I woke up. In fact at many points of the dream I was thinking "maybe I am dreaming" but then I kept thinking..."no I am just crazy", so that rational kept it going for pretty damn long. I also had the feeling that I have had that dream before. Any of you guys have repeating dreams as weird as this?
