Is it possible to visit or make a reoccurring setting like for example a personal mansion with like an indoor pool and other indoor stuff, luxiciourous cars, and etc. (I know for a lucid dream that example sounds dull when your imagination is the limit but still)? Also is history set in stone or it just happens and their, like for example if you beat the hell out of a DC will he or her pledge vengence? (I have read DJ entries and I've had one short LD I just want to know if all this is possible, thanks)
