A Slayer will frequently dream of herself as a Slayer in another time and place. These dreams are usually vague, but can also be prophetic. Dreams exist in their own mystic plane or "dreamscape" where for a Slayer, precognitive sense and the inherited memories of other Slayers can manifest themselves. Also, Slayers have been shown to appear in each other's dreams, and Buffy and Faith shared several dreams while Faith was in a coma. Faith provided the first cryptic reference to Dawn Summers' arrival. Melaka Fray, the Slayer of the far future, lacks these abilities. Due to the unusual nature of their birth, her twin brother received these visions instead. Other abilities While a regular person may require eight to ten hours sleep, a Slayer seems to require considerably less but needs some rest to function. Buffy herself has been seen as staying awake for days although she will usually "crash" and sleep for half a day and show no lingering disabilities. A Slayer naturally has formidable fighting skills. Buffy is shown to easily fend off multiple vampires at the same time while under a memory loss spell, with no memory of her combat training—relying entirely on her natural Slayer instincts, presumably indicating an instinctual grasp of fighting. Dana is seen holding her own against Spike without having any previous combat training. It is also shown that Potential Slayers have innate skills in combat, even before being called, as Amanda was able to defeat a vampire without any previous combat training in "Potential". The Slayer's Watcher trains her to hone these talents, and to teach her specific fighting skills, such as various martial arts. The training helps her to battle the occasional demon whose physical strength outclasses her own. For most situations, however, her strength suffices. To test a Slayer's natural ingenuity and practical capability, the Watcher's Council administers a test known as "the Cruciamentum" if/when they turn eighteen, which strips the Slayer of her powers and forces her to fight a powerful vampire without them ("Helpless"). The compound used to weaken the Slayer makes her typically weaker than most normal humans. This renders a Slayer who would still normally be physically fit without her powers remarkably feeble even for a human. This forces the Slayer to rely solely
