      I presume stones get cold during night, when temperature rise they remain colder than air so water in the air condensate on them. Why is this wanted? Well, to get drinkable water in dry areas?

      Condensation. Stone wall is cold in the morning, humid morning air passes through it, water condenses on the large, cold surface, and drips down.
