The dream species' homeworld was an inhabited planet in the Delta Quadrant. It was the homeworld of the dream species.

After being under assault from the dream species in 2374, USS Voyager found the planet less than a light year from its location by detecting a neurogenic field emanating from beneath the surface of a planet. (VOY: "Waking Moments")

According to the Star Trek: Star Charts (p. 88), the planet, named "Dream World" in this reference work, was located in a trinary system of M-class stars. Voyager visited this system on stardate 51471.
