A child
Psychological (Freud)
A child in a dream often points to one's inner child, to unlived needs, early wounds, or a vulnerable, still-unfolded side of the self. It may equally express a wish for a fresh start or for innocent vitality.
Oriental reading
In the Oriental tradition a child is read, according to the dream's mood, as a sign of joy and increase, or of worries and small, demanding obligations. A beautiful, laughing child is mostly taken as a good omen and a source of happiness.
People
Dream interpretation is for self-reflection and entertainment — it is not a medical or psychological diagnosis.
