The figure that I have heard is 90 minutes for each sleep cycle, although I believe that is only an approximate number. During each cycle, you experience stages of light sleep, deep sleep, and REM, with anywhere from four to seven sleep cycles per night. People often tend to sleep in hour-and-a-half increments; because of the length of sleep cycles, it is sometimes easier and more pleasant to wake after seven and a half hours than a full eight.
As to the original question, it is rather difficult to relate it to actual experience. Generally during the times when I have slept for long periods (due to illness or some other cause) it has been a light sleep much of the time during which I would often briefly wake long enough to be aware of my physical surroundings. It is hard to conveive of a period of sleep that is both extended and uninterrupted. That said, I suppose the most logical answer is the general consensus--that the sleeper would dream.
Let others believe in the God who brings men to trial and judges them. I shall cling to the God who resurrects the dead.
