Every baby is new to the world, and vice-versa. In particular, and quite logically, a newborn baby symbolizes purity and innocence, which we have more or less lost as growing up and are keen on returning to in the rest of our life.
We were seldom, if ever, get ourselves emotionally involved or agitated by delusions when we were babies, being otherwise a true master of our own lives with merely called as baby. On the other hand, as a physiologically functional adult, we frequently choose from moment to moment where we focus our attention and what we tell ourselves about the fours corners of the world. Being attached to the sense of control over the circumstances, we felt panic and lost when the control seems to slip over.
Thus it is very true that a sleeping baby is able to awaken the world, and when I capture a sleeping baby, I may be able to wake up.
