Actually, you have two cycles, like everyone else. A long cycle that is indeed 26-28 hour long, which makes sure you sleep every once in a while that is pure time based. And a short cycle that syncs to light.
These two cycles interact in complex ways, but the gist of it is that if you fuck with it by staying in a dark room with no lights but screens, it ends up being pretty random, with 26-28 hour long days.
