Dreamscape

Shardra Geltl, Sajan Gadadvara, and Rivani sail on a strange ship in a dream voyage through the Dreamlands.

A dreamscape is a realm within the Dreamlands similar to a demiplane, and is created by a sleeping mortal creature; this creature is typically the only creature who can naturally access it. A dreamer inhabits a dreamscape through a lucid body, a type of avatar. Due to the vast array of mortal life in the multiverse capable of experiencing dreams, the Dreamlands can contain an almost countless array of independent dreamscapes.

Planar traits

Due to the unusual dimensional behavior of the Dreamlands and its existence within the Ethereal Plane, a dreamscape can be considered to be coexistent with all other planes.

Each dreamscape has its own planar traits, which can include properties of physics such as gravity and time. The perceived passing of a single day in most dreamscapes consumes an hour in the Universe.

A lucid body can attempt extraordinary acts within a dreamscape that they could not accomplish in the Universe, such as casting powerful spells or wielding legendary magic items.

Access

Aside from entering a dreamscape through a naturally occurring dream, existing dreamscapes can also be accessed through specialized magic spells and powers, such as dream travel. Accessing someone else's dream is a more difficult task of planar travel than accessing the more stable Dreamlands, which itself is more difficult than traveling to other standalone planes.

Animate dreams are creatures that escaped from dreamscapes and often inhabit the Ethereal Plane.

Dreamthieves

A dreamthief is a rogue whose soul contains a dreamshard of concentrated emotion that grants them supernatural access to others' dreamscapes, and can manifest and then steal those creatures' own emotions. They can also dream lucidly.

Known dreamscapes

• Leng, an unusually stable dreamscape that became a demiplane accessible through specially tuned planar tuning forks
