Tel'aran'rhiod (tel-AYE-rahn-rhee-ODD; Old Tongue: The Unseen World), also known as the World of Dreams and the Wolf Dream, is a parallel world where all the possibilities of the Wheel of Time connect, and it is linked to all the myriad such worlds that exist within the Wheel. It is both of those worlds and apart from them, and is occasionally entered for a few seconds at a time by ordinary people dreaming, although there is great risk to those who do so as imagination becomes reality in the Unseen World and what happens there happens in the normal world as well. There are people called Dreamwalkers who have the ability to enter Tel'aran'rhiod at will, and they are able to exert varying degrees of mastery over its strange and malleable nature.
