I have had dreams where I was pretending to do things and objects appeared. FOR EXAMPLE, I would be dreaming about pretending to stack shelves and an item would appear.

One prime example is I once had a dream about being on a ship with a wooden sword and I was pretending to fight Anikin Skywalker, and I had him cornered and I told him "surrender your light sabre" and I knelt down and picked it up, though I kept my wooden sword.
