Your sleep disorder is keeping you awake at night, and it's giving you lots of time to think. This is why your "babies" are shown hiding inside your mattress. All that time that should be spent sleeping—is spent worrying about your kids!
Your son's recent hunting trip, in real life, is a symbolic initiation into manhood. Your "baby" is leaving his younger years behind, on the path to developing as a man. As a result of his trip you missed your usual weekend together, which is a foreshadowing of future separations. In the dream your son is represented as a baby and as a pacifier, both of which you must hold tightly to prevent from disappearing. Now that your 15-year-old is growing into a man, do you feel a precious time in your relationship drawing to a close?
At the same time that your son is beginning to assert his independence, your thoughts have wandered to making contact with your two older children, now in their 30s, who were adopted at birth and raised by others. In the beginning of your dream, you and another woman deliver the babies but somehow they disappear. Significantly, there is no grieving at their loss, and you "both seemed to be OK with it." The feelings in the dream almost certainly reflect your feelings at the time of adoption, over 30 years ago. When you placed your children up for adoption, you knew it was the right thing to do.
Your dream reflects fears of being separated from your 15-year-old son that have grown to encompass your desire to make contact with the children you placed for adoption. If you do decide to contact your birth children, you may wish to visit Adoption.com an extensive online resource not only for birthmothers and adopting couples, but also for children who wish to reunite with their birth parents.
