My main goal in lucid dreaming.

This is the goal, I have my mind create a mansion, then I go inside and reshape it for however I like. Then I put whatever I want in. Then in other lucid dreams if I find something cool as im exploring, like a tree with tasty and other worldly fruit. I would get a seed and bring it back to the house and grow them. I know I could just create them out of thin air but this would be more fun. Or if I found some non real animal. I could bring it back as my pet. The only problem is that it seems very hard to do unless you are advanced at lucid dreaming. But I can wait, i'd rather have it happen when I can see the dream more clearly. What do you guys think about this idea, I wanna hear your comments.

That sounds like fun! I think it wouldn't be too hard, especially if you aren't creating anything consciously, just letting your subconscious create it.
