Collies go to bed early

Of a evening the Collies go to bed while I watch TV . The problem is they wake up around 3:30 am and usually wake me as well. I have always got up early (but not that early). I can usually go back to sleep by playing possum. They watch me for about 30 seconds to see if my eyes are open or any movement, if not they go back to bed. If they detect movement the day has begun.

Any of you experience this behavior with your dogs?

Part of this behavior was because I use to get up at 4:45 for work, retired now and would like to sleep in until 7.
