Seeing a boy in your dream signifies a hint of good news. If you dream of giving birth to a boy, it may indicate thoughts, understanding, or a sign of illness. Conversely, dreaming of giving birth to a girl suggests relief from worries or a reduction in stress. These dreams reflect various situations in your life and indicate changes in your mental state.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Boy" (page 53).
Seeing a young boy in a dream means receiving glad tidings. Begetting a boy in a dream means worries, burdens or sickness, while giving birth to a girl in a dream means relief from distress or easing of one's difficulties. Carrying a young boy in a dream means carrying burdens. Giving birth to a boy in a dream also could mean having a helper. A beautiful looking young boy in a dream also signifies good luck and victory over one's enemy. Seeing a beautiful looking boy in a dream means that beautiful and pleasant things will take place in one's life, or it could mean satisfying one's needs. If one is called a teenager in a dream, it signifies the necessity to take a ritual ablution, or that something good or bad may take place in wakefulness.
