Something that resembles a dream, often feeling vague or unreal.

Dreamlike → It is formed from "dream" (from Old English *drēam*, meaning a series of thoughts, images, or emotions occurring during sleep) and "-like" (meaning resembling or characteristic of). The word "dreamlike" describes something that resembles a dream or has qualities associated with dreams.
Think of something that 'resembles' ('-like') a 'series of thoughts or images during sleep' ('dream') — that's why dreamlike means having qualities of a dream.
