Expiration in a dream signifies the end of something that is close to you. The end of a relationship, the end of a business venture, or even the death of a loved one can all be often represented by this dream symbol.
The end of something is never easy and it can be really hard to let go. In this case, the person who dreams about expiration may need help with letting go and moving on in their life emotionally.
Also, the dream may symbolize that there is an expiration date on something so you need to take care of it soon, such as getting your insurance renewed or visiting with family before they pass away. It could represent the inevitable countdown to the future when everything will come to an end.
