Dreamlandish
Dreamlandish is the term for the language regularly spoken in the Dreamlands. It is a mishmash of Earth-based languages with many strange alien dialects, some of which are or at least local only to this world. Many of the local creatures will understand it, and maybe even speak a bit of it themselves. Any dreamer, or person who physically enters the Dreamlands can understand it. It appears as if the place itself renders the creature capable of reading, writing & speaking it.
