I believe that dreams are what influence us because if we had a nightmare when I woke up I will feel depressed, sad or worried all the time. But if we dream, when I woke up, we would feel more comfortable and happy specially.
.The dream, it is what we see today. The documentary included a life of one. So when we see only while we sleep, that's all. Is that when wake up from a dream then.This is a real dream.
