To dream or not to dream

I dream every night sometimes the dreams are crazy and other times the dreams are very simple and boring. Now dreams are hard to remember because you forget most dreams 15 seconds after you wake up so even if you didn't think you dreamed the night before you did. When i dream i dream in the first person so im controlling who ever i may be, sometimes i go around like its my normal life. Other times im running away from zombies or experiencing the end of the world and then all the sudden there would be clear sky's and everything i normal.
