IS IT NORMAL NOT TO DREAM?

I was wondering if it normal for someone not to have dreams. I could recall sometimes ago when i don't dream...although I do think about something before I go to bed and at times,watches night movies but then I never dream.
When you sleep and don’t dream,this implies that you go back to your original source. You do not exist any longer as an individual. You come from nothingness and you go back to nothingness. That’s why there was no recollection of anything because there is no “YOU”. The world disappears in your absence. This kind of situation seems normal when you are a baby, but abnormal as an adult.
The process of dreaming is the sub-conscious way of cleaning house and if it didn't clean up rather regularly,,,profound insanity could result. At times, one could probably be in a very deep REM(rapid eye movement) sleep and simply don't remember your dreams.
So if you feel you don't dream,perhaps you should try this techniques;
if you want to remember your dreams. start with keeping a journal / diary right beside your bed. as soon as you wake up in that half asleep half awake state... see how much of your dream you can recollect, then write it down as soon as possible. The more effort you expend at those kinds of tasks the more you will find yourself remembering.
You can also try setting your alarm. maybe half an hour before you are due to wake up or something like that. you want to try and catch yourself during an episode of REM sleep.
