No dreams in deep sleep.

We never dream in our deep sleep. While the sleep is interrupted by the sub conscious only we start dreaming limitlessly. We get ideas at this point. Some times we see sceneries which we have never visited and also our usual surroundings. People known to us and unknown to us appear in our dreams. We come across all kind of living beings too. We used to cry, shout, and get angry and so many things like these. We do not understand as how we come across all these. We are unable to believe them as true. Some people claim, that they have actually experienced them. All these seem to be happening without our knowledge.
