Nightmare – A nightmare is a very frightening and disturbing dream, revealing some of your deepest fears and apprehensions. Of course, the actual meaning of your nightmare will depend on the individual symbols in your dream. You will need to look up these particular meanings in order to understand the meaning of your nightmare. It is worth noting, though, that you need not assume a nightmare is a foretelling of calamities to come. While prophetic nightmares are certainly possible, it is more likely that your nightmare is a sign of the tension, stresses, and fears that you deal with every day.
