Yes, participants of a traditional three-year-retreat (in the tibetan tradition) are known to have a significant lower need of sleep. After a few weeks or months, it settles somewhere at about four hours per night. A secluded retreat atmosphere, wich provides little sensory input, and the amount of meditation (~12 hours a day?) seems to do the trick.

Could you share your experiences...
Once, on my way home from a weekend lecture course with a tibetan lama (Mingyur Rinpoche), I fell asleep in the train, but continued to be aware of my mindstate and the remaining sensory inputs (especially sounds). Mingyur Rinpoche mentioned a technique called sleeping meditation, and I tried to apply it, which seemed to have worked. Check out: http://www.mengstupiditis.com/2009/05/m ... ongey.html
Sounds similar to what Ben mentioned, doesn't it?
