On Dreams

People dream because of a number of reasons. Some because they have some unresolved issues or concerns while others dream because of stress. It is said that we act out in our dreams our unfulfilled desires. There is also a contention that even fears and negative emotions may find its way into our dreams. I have also heard that there are people who experience lucid dreaming. This happens when one is half awake and can control in a way what transpires in the dream.
