To dream of junk represents feelings about areas of your life being uninteresting or pointless. Feelings about someone or something being a “loser.” Something in your life that you have a low opinion of. Something in your life that you believe is useless. Ideas or methods that don’t work.
Alternatively, junk in a dream may reflect your expectations of something being worthless. Possibly a warning about overlooking ideas or possibilities that don’t seem valuable at first. Overlooking something or not giving something a closer look because it’s not exciting or getting a lot of attention from others.
Negatively, in a dream may reflect arrogant beliefs about someone or something not being worthy of respect. Not liking something because you can’t showoff with it.
