After time skips again, Charlotte's condition worsens

Just after Locke, Miles, Charlotte, Sawyer and Juliet skip through time again Charlotte begins seizing and bleeding from her nose. She falls on the ground and Daniel turns her over and holds her looking deeply saddened and scared to death.

Seeing as Charlotte's condition is so similar to what happened to Desmond and Minkowski, it seems that the skip in time triggered this episode. It happened only moments after the skip. Her consciousness doesn't seem to be traveling through time like Desmond in "The Constant," so what is happening to her?
