What does it mean to dream about sandwich?
A sandwich usually stands for everyday sustenance, convenience, and things held between two sides.
Four ways to read it
Each reading below comes from a named tradition and a cited source, so you can see where it came from and decide what fits your dream.
Freud
Freud would read the sandwich as plain, portable nourishment, the practical meal of the working day. It can carry an appetite for the simple and sufficient rather than the indulgent. The filling, or its lack, may say what comfort you seek.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung might see the sandwich, with its filling held between two slices, as an emblem of being caught or contained between two sides. It can mark the everyday or a feeling of being pressed from both directions. Ask whether you feel nourished or squeezed.
Jungian concept (our summary).Modern
Continuity ties the sandwich to waking thoughts of lunch, work, and ordinary routine. It may simply carry over the rhythm of the day. Whether it felt sustaining or hurried can colour the meaning.
Continuity hypothesis (our summary).Mythological
The sandwich takes its name from a later age, but the bread that holds a filling joins the old tradition of the portable meal carried to the field or the road. In that sense it belongs to the long custom of bread as the traveller's staple.
