Tel'aran'rhiod

Tel'aran'rhiod (tel-AYE-rahn-rhee-ODD) or the World of Dreams is a fictional reality where the reality is mutable, mentioned in the fictional world of Robert Jordan's fantasy series The Wheel of Time. The word itself is from the in-universe language known as the Old Tongue, literally meaning 'the unseen world'. In Tel'aran'rhiod dreamers are self-aware, and environments are malleable, depending on the awareness of the dreamers. Additionally, the perception of time in Tel'aran'rhiod is different from the awaking world.
