Yes, I remember you had a similar dream and even looked it up. That dream was posted in April of 2010. I wonder what has caused this powerful man to re-appear in your dream now.
Can you think of anything that was going on then that is similar to what is happening in your life now? Also in your prior dream you did have an affair with him and got pregnant.
The affair is most likely symbolic of how you want to become a more powerful person. The pregnancy I'm guessing is an idea, thought, or course of action you can take towards becoming more in control. In this dream you are part of a group of decision makers that are close to the president. You mention riding in an elevator together, and being a passenger in a car with him driving.
OK from the information that you give, I see the group breaking from the meeting getting into the elevator, going down to the ground floor and then driving off.
The group refers to different aspects of your character and personality. Although elevators can mean different things, I took it to mean that the presidents role in your daily life is more of a subconscious one(going down). The next image shows how he is in control, while you are only a passenger.
(Living in a Latin American country I think it is safe to assume that men hold most of the power. This belief has been with you since before you were born, as a womans emotions are felt by the child she carries.)
The next dream involves a party or celebration. Usually this type of event indicates some accomplishment in your real life, either that has already happened, or that you expect to happen. It may also mean some sort of emotional release.
Some women bring in many plates of food. To see food in your dream, represents physical and emotional nourishment and energies. (The different types of food can symbolize a wide range of things.) There are so many offerings that you don't know what to do with them all.
To me I see the food as gifts that you have. They are brought by women, all aspects of you. They represent physical and emotional gifts that you have. But they are not for you alone. They are given to be shared. I believe that you have many gifts that can help other people. In fact so many that you don't know what/how to use them.
You have stated that English isn't your native language so I assume that you don't dream in English but in your native tongue. Then you have to convert that into English. That alone is an accomplishment. Being bi-lingual is an advantage that I wish I had, and can place you in many positions of both service and power.
In this dream you are again part of a group at a picnic.
I see the picnic as a more relaxed informal setting. You are sitting on a blanket which indicates being grounded yet comfortable. You are eating, which I take to mean you enjoy this kind of activity (relaxed, informal)as it gives you nourishment. A woman nearby tells you "You are kinder than your children". You react in anger.
I must admit this part of the dream has me confused.
Are you defending your kids?
Are you saying that being kind is not a good thing?
Are you expressing your feelings that in being kind you have been walked on, or taken advantage of?
What I do see is that the woman is trying to complement you and you totally reject it. (complete idiot)
This is part of a reoccurring theme in your dreams.
In one you accidentally pee on a woman who is underground.
In another you try to strangle a woman you are mad at and fear being lynched.
So what I'm seeing is that you have negative beliefs about yourself and women in general that are keeping you from growing and developing into the person you truly are.
I hope this helps you. Also If I ever write anything that angers you, let me know rather then letting it build until you can't hold it in any more. You can always e-mail me through this forum if you don't want to post publicly.
