At night, the baby was in his mother's arms and talked about the little memories in his mind.
The mother patiently explained to the baby what a dream is.
Babies aged 0-3 years old can dream. The baby vaguely recalls the scenes in the dream and cannot distinguish between reality and dreams.
Under the mother's explanation, the baby understands that dreams happen when sleeping, and dreams are not reality. Everyone dreams, and so does mother.
