Hi starz, welcome to DreamViews! ^_^

The other realm idea is very cool, you might be interested in Hyu's dream journal, since his dreams seem like other realms: Lucid Dreaming - Dream Views - Hyu's Adventures - Dream Journals

A lot of his lucid dreams take place in what he calls "persistent realms", it's basically a dream-scape and dream characters that stay the same. He has a lot of cool DCs he goes on adventures with and the dream worlds he visits are very cool.

See you around the forums~
