Having lucid dreamed nearly on demand for two years, then spent several months too tired for dreaming, I've returned to inducing lucid dreaming but not for the purpose of senseless fun.

I consider myself quite a creative person. Recently my dreams have become a tool for creative purposes. I've always treated my dream world as a sort of virtual reality, so currently I tend to get lucid and build shapes and objects, or sculpt things for fun. I've always been interested in building things in dreams, I've talked about it before, but I've never really gotten any strong advice on the subject of world building.

I intend to start small, by fabricating a room. I was wondering if anyone has any tips on keeping objects in dreams to hang around for longer. I've decided to keep the scene simple so my mind can keep record of what is around me. Is there anyway I can increase the chances of a dreamworld to stay persistent for a little longer than the usual, which seems to be turning around and things disappearing.
