Your idea sounds great! In ETWOLD Stephen Laberge describes under the Chapter "Creative Problem Solving" How one could "build" his own "lucid dream workshop". Since I read this I have an similiar wish to yours, I want to build my own dream house with a specific landscape around (I don't want to go into depth here it is your Workbook after all), that I can easily access later through incubation, or if lucid changing the dream scene to it. Anyway, I wish you great success with your Island, hold me up-to-date The idea with the waterfalls is great! I will probably try something similiar when the moment has come, though probably with simple doors. Also I will probably try to develop two DCs in my dream base who I hope will always be there when I visit it, a Butler and a creature.

I am excited to see if this works, but if you say you know from others who created similiar things before and even Stephen Laberge writes about it for solving creative problems, I believe that it is possible to create such places.
