Chiefly, the mystics that might write something like a dream dictionary would put much emphasis on the hands, the eyes, and the mouth. Many of the dreams that people have, have an underlying meaning that gives regards to the fact that they need to open up more methods for communication with others. In a world that is becoming more internet based and technologically driven, it is becoming easier and easier day by day for someone to cut themselves off from the outside world, and to retreat into the recesses of their homes, and it is because of this that people have so many dreams telling them to communicate.
Now, because the phone has become the chief method for communication, people do not see eyes, mouths, and lips the same way that they once did, and now the meaning of dream about lips will be significantly different than a dream about a phone. Now the phone is the most common symbol you will see in a dream if you have problems struggling with communication, and this is one of the most popular dream interpretations.
As always, the most accurate dream interpretation will come from those that are most in tune with the happenings of their dreams and that can recall the minutest details. For example, it is not enough to simply remember a phone on a dream, but to get the real dream meaning of this symbol, the best thing to do would be to recall who was calling who. If the person in the dream was calling you, it could be a message that you have not been as dutiful as you should have been in your relationships. For example, if your mother is calling you in your dreams, then perhaps you have not done as you were told recently. Or you have not been over to see her often enough and this is eating at your conscience. If it is a friend calling, then the dream meaning of this could be that your friend is not seeing enough of you. You have not been doing a good enough job of sticking to your friend relationships.
Alternatively, if you are the one calling the friend in the dream, then the dream meanings would be almost opposite. If you are the one calling your mom, then it is you that needs attention. You feel that your mother has let you down recently and you want to establish contact again. If it is a friend you are calling then you may feel that they have not lived up to their duties as a friend and you need them to attend to you. Everyone can get a little bit lonely in life, and dreams involving telephones are usually the greatest indicator that someone is lonely. Whether it is the dreamer, or a friend or associate of the dreamer, a dream about phones indicates that something needs to be done to maintain a relationship. Try calling someone the next day.
