Dream 3: maternal miracle

last night i dreamt that i heard a baby cry out, i don't know where i was, maybe in a mall or something, there were people around, their noise in the distance. there was a woman standing on my right and she told me: "look, you've lactated!" i looked down and sure enough my left breast had dampened my turquoise cotton turtleneck with a dribble of wetness.
not being pregnant and not having any children, a feeling of wide-eyed incredibility and beauty came over me, and i started to silently cry.

that's all i remember.
i think this scene was triggered by something i read and i can't figure out what!...
