What is a Dream?

Hi, I am back again. People refers that when you are sleeping and see things. It's a DREAM. Ok, for me it's different. I would never sleep if I don't dream. I used to think that is a trick of the mind, like after everything you have been throught your journey, when you go to sleep your mind collect what he had captured and make a movie out of it. However, I am starting to think that mine are diferent. Iike for instance, I went somewhere with my family and we got lost because it was the first time and all of a sudden I am telling people where to go and what to do. They were shocked when I told them I've been here in my dream before. I have seen things in my dream that will stuck in my head for life. I have three dream that I am gonna explain if I have space. I went to bed and found myself into another world. I am not kidding, and I remember everything I did, and how I got in that world. but one thing tought, I can't never remember the faces of those friend who took me them places.
