Time flash
From Lostpedia
These flashes are accompanied by a flash of white light after which those effected travel to an apparently random time. Both the time traveled to as well as the time between flashes seems completely random. Objects being carried by people who experience a time flash also seem to travel with them. Besides the survivors of flight 815, those who have been seen experience time flashes include Juliet, Charlotte, Miles, and Daniel Faraday. Juliet seems to be the only one of the Others to experience any time flashes.
Nosebleeds and headaches seem to be a side effect of these flashes.
