Found several references to studies where the participants where kept underground and/or controlled environments. I distinctly remember reading about a woman who spent several months underground in one such study who suddenly went from a "normal" 24 hour CR pattern to one that she doubled her sleep/waking times automatically. I vaguely remember that this study they didn't artifically turn on the lights and such but only when she woke up. And she had no idea that she'd switched to this elongated pattern -- to her she was sleeping the same amount of time as before.

And then there was some vague mention of 1 or 2 researchers who spent lengthy times(years?) in caves, who had some unusual experiences.
