The Complete Guide to Interpreting Your Dreams

by Stearn Robinson - Tom Corbett
The meaning depends on the sex of the user.

If it was a man who used the profane language in your dream, you can expect a temporary decrease in your income; but if the profanity was used by a woman, you are being warned about a casual love affair which could develop into a serious embarrassment unless you are extremely tactful.

Try to remember that, when you are through with (or tired of) someone, it is a safer policy to lay him or her aside than to throw him or her away.

Ten Thousand Dream Interpretation

by Gustavus Hindman Miller
To dream of profanity, denotes that you will cultivate those traits which render you coarse and unfeeling toward your fellow man.

To dream that others use profanity, is a sign that you will be injured in some way, and probably insulted also.
