醉 (zuì): Drunk, intoxicated. The radical 酉 (yǒu) represents an ancient wine vessel, indicating a connection to alcohol.
生 (shēng): To live, life, to be born. It depicts a plant sprouting from the ground.
梦 (mèng): Dream. A character that represents the ephemeral and unreal state of dreaming.
死 (sǐ): To die, death. It shows a person kneeling beside a coffin, symbolizing the end of life.
These four characters combine to create a vivid and poetic image: To live (生) as if one is drunk (醉), and to die (死) as if one is in a dream (梦). The meaning is that the person's entire lifespan, from birth to death, is spent in a state of confusion and unconsciousness, without ever achieving anything meaningful.
