Do Babies Dream?

    Q & A

    Q. Do babies dream?

    A. "Yes, as far as we can tell," said Dr. Charles P. Pollak, director
    of the Center for Sleep Medicine at NewYork-Presbyterian/Weill Cornell
    hospital in New York.

    Most dreaming occurs during a type of sleep called REM sleep, for
    rapid eye movement, which Dr. Pollak explains is "an evolutionarily
    old type of sleep that occurs at all life stages, including infancy,
    and even before infancy, in fetal life."

    There is no question that newborn infants have REM sleep, he said, and
    the rapid eye movements can be observed as they sleep. The two eyes
    move together, mostly side to side, but sometimes up and down.

    It is a well-based inference that babies are dreaming in REM sleep, he

    As for the content of any dreams, Dr. Pollak said: "That is like
    asking whether your pet dog or cat is dreaming, because they can't
    communicate, and you can't ask. We presume that infants dream
    infantile things, but we don't really know what it is that they

    "There is some evidence in adults that the direction of eye movement
    corresponds in a crude way to the content of the dream," Dr. Pollak

    "If they are dreaming about walking in a field," he said, "the
    movement is most likely horizontal. If they dream of looking up at a
    building or climbing stairs, vertical eye movement is more likely to
    predominate. We can't go further than that."
