A Galactic Nightmare is a ghost type alien. There is one in every galaxy even in the milky way galaxy, thats why we have nightmares. But the one that attacked Borg 10 and his team was stronger then that of earth. He can give nightmares to any one that is sleeping that could kill any one. This particular Galactic nigtmare was killed by Dreadskull.
