LiveScience quotes studies suggesting video gamers, like Franz Ferdinand, have a predilection for lucid dreams, saying this might "provide an edge when fighting nightmares or even mental trauma," though one researcher cautions "the findings represent suggestive associations rather than definitive proof." That said, they are also exploring the implications this has on PTSD sufferers: "The gamer dream experience of high aggression levels matched with little or no fear inspired Gackenbach to pursue a new study with Athabasca University in Canada. If gaming can act as a semi-protective function against nightmares, she reasoned, maybe it could help war veterans who experience post-traumatic stress disorder (PTSD) after enduring combat."
