Dreams can often be murky and unclear, but sometimes by digging deeper, you can piece together things that make sense. If you are packing up boxes in a dream or moving boxes and not really knowing what it's all about because you have no plans to move in your waking life, it could be a sign of what's to come.
According to Dream Astro Meanings, packing is often an indication that a big life transformation is either going to take place soon, or your brain is indulging in considering how a huge life change may look and feel. In your dream, you may find yourself placing items into a box, moving boxes, or even watching other people pack up.
Oddly enough if you are watching someone else move, it can symbolize that you are too caught up in someone else's life, according to Miller's Guild. It's pretty common to become overly involved with a family member or friend's business, and that's usually a sign that we're not focusing on our own. A dream of being involved in someone else's big life move may be a reminder that you need to refocus on yourself.
