ELI5: Why does the taste of water change depending on your level of thirst?

I heard it has something to do with your brain sending out signals to the rest of your body, taste buds included.
Your body need water to live, to survive. When you are super thirsty, water mostly taste sweet. Your taste buds trick you so you would drink more water.
