Hi Himadri_sm
I suggest you try to fix your sleeping pattern up. Our body is designed to sleep when it's dark, sleeping whilst it's light extremely effects the chemicals such as melatonin that help you to get a good's nights rest. Your body runs on a cycle called circadian rhythm, this circadian rhythm refers to our internal, approximately 24-hour cycle of biochemical, physiological, and behavioral processes. If this cycle is out of whack, as your is. It will be difficult to get and maintain a deep sleep.
Now I don't suggest you suddenly go to sleep at 10pm tonight, but what you should do is begin a process of changing your sleep pattern. So instead of 6am, go to sleep at 5am. Then set your alarm to go off at 3pm, this will give you 9 hours of rest. Even if it is disturbed, get up at 3pm. The next day change it to 4:30am and wake up at 2:30pm. Keep doing this (30mins earlier a day) each day and hopefully you will gradually be able to fix up your circadian rhythm and start to feel refreshed of a day again.
ok i forgot to add..when i wake up from my dream my mind is filled with a scene from either the game or the movie...its like i am half asleep ,half awake...then i fall asleep 7 after about an hour the same thing happens again..
