Help on designing your dream environment

[Cetos]

I think there are ways to do this, like falling asleep imagining the environment or something, but I want to try to go off of something as specific as I can and really have something to work on. Is there like a certain way to do this using a specific method, like maybe using a DEILD to design it? Thanks a lot. *edit* what i mean by this is like maybe imagining an exact location or monument somewhere, and completely designing the dream, if that's possible. thanks a bunch...
