Short dream meaning is explained below using 3 different sources. Each interpretation is shown with its source.

Interpretation 1 — Dream Explanations - Anonymous

If you dream that something or someone is short, then it represents having little importance or a shrinking value to you.

A diminutive adult in your dream might also represent connection with your inner child, and that you are feeling vulnerable.

If you dream of being short and of someone else being tall, then you are processing feelings of inferiority, powerlessness, and intimidation. If, however, you dream that you are tall and someone else is short, then this dream expresses your feelings of superiority, power and domination. Consider the feeling tone.

See Size and Dwarf.
