Okay you made me start on this. DreaMs sometimes show you what "IT" wants. Sometimes it shows what YOU want. Sometimes it shows you what you fear the most. Someone it shows you what you love the most. Basically its an encyclopedia of yourself and in the same time biography. There are no such things as nightmares cuz nightmares are still dreams , dreams in which you see what you fear the most or what you were afraid of. For example you're a kid that smokes , after some time you dream smth about smoking somewhere and you just feel like your parents know it and you're frightened and always when you wake up it's like "oh it was JUST A DREAM" . Another example is for example if someone did something really bad to you take you hostage beat you to death or smth like that its only natural that you experience the same thing again in your dream. If you want more informations about dreams you can always pm me so i can explain ! :)^
