Narrative:

I was single plting a C-208 caravan hauling cargo from pilot-cbe airport. Taxi, takeoff and departure phases of flight all uneventful. Sometime during cruise and heading direct grv VOR, I apparently fell asleep at the controls with the autoplt engaged. I estimate that I was asleep for approximately 45 mins at which time I passed 130 mi southeast of cbe at 5000 ft and heading 120 degrees. I woke from sleep hearing my call sign over the radio from another airplane. The person talking to me asked me if I was ok at which time I replied yes. He advised I execute a right 180 degree turn and gave me a frequency to call. I called and was advised to proceed direct to dca VOR and navigated uneventfully to cbe thereafter. Some type of airspace violation may have taken place, at present I am not aware of any. I have not been able to receive any factual information about any violation presently, knowing only that my position upon waking was 130 mi southeast of cbe heading 120 degrees at 5000 ft.
