The World of Dreams, also called the Unseen World, a realm that permeates and surrounds all other possible worlds. It is accessible through dreams, certain ter'angreal, or by entering physically using the One Power. Injuries sustained in Tel'aran'rhiod are real, and death there is final. Time and space work differently - locations can be reached by thought alone, and 'need' can guide a dreamer to what they seek. Wolves call it the wolf dream. Among the Aiel, Wise Ones called dreamwalkers are skilled at navigating it.
