Furniture under dust sheets stands for a part of life put on hold or closed off. Tradition reads lifting the sheets as returning to something left untouched for a while.
Has this come up in your dreams before? What was going on in your life then?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
