Psychology
A can preserves its contents, so it points to preparing for hard times or feelings put off for later. Hoarding cans shows worry about the future; a can you cannot open, emotions stuck inside; a rolling empty can, a sense of hollowness.
Folklore and history
Canning spread as a way to preserve food around the 19th century, supporting long voyages and emergencies; many Japanese homes keep cans for disasters. Old lore is scarce, but modern readers see a full can as savings and an empty one as waste.

This site's view
In this site's view, the label is key. A can with no label holds a memory or wish you have nearly forgotten; an expired one means it is time to open or discard an old plan. Kicking a can hints at longing for childhood freedom.
Going deeper: our reading
In many Japanese homes, pretty tins from sweets are kept after the treats are gone and used to store letters, photos, buttons and small treasures. Some of us collected secret treasures in a tin as children. Tins protect food, and they also hold memories. In this site's reading, opening a can to find something nostalgic means it is time to reclaim forgotten loves or old dreams. Being unable to open it without a can opener suggests your heart feels that sealed-up feelings need someone's hand or a small push to open. This is our speculation, but a can that rattles when shaken yet feels too frightening to open shows you know certain memories are still there, even if you are not ready to face them. Some days, simply hearing the rattle is enough.

Turning a bad dream
In Japan, people once tried to turn a worrying dream for the better: a baku charm under the pillow, telling the dream to a nandina bush, or reciting an old dream-turning poem. Read the column on dream trading and dream-turning
