If a person dreams that he has dug a well in his house or he merely dreams of a well present in his house and such a well swells with water it means that Allah will grant him much barakah in his wealth and such wealth will become a means of earning him increased livelihood without much toil and hard work.

In the above case if the well is seen sending froth all its water until it becomes exhausted, it means he will lose much of his wealth with very little remaining.
