Backpack

Backpacks in a dream are associated with events in the past.
A backpack is a bag with shoulder straps which is carried on the back. It is commonly used for hiking or traveling. If you dream of a backpack, it implies that something must be weighing you down. You are carrying a burden on your shoulder, which is proving to be too heavy for you and you need to put it down before it makes you fall down. It represents the unfinished business in the past which you are carrying with you in your present, into the future.
