夢

How it works

The adjective いい (good) sits right before the noun it describes (夢(ゆめ) (dream)) — just like English. を (object) marks the dream as the object, and the verb 見る(みる) (see) shifts to casual past 見た(みた) (saw). Japanese literally "sees" a dream rather than "having" one. With no polite です (is) or ます (polite), it sounds relaxed.
