Sirach 34:6-10
{34:6} For your heart suffers from imagination, like a woman suffering in childbirth. Unless it is a visitation sent from the Most High, you should not set your heart upon it.
{34:7} For dreams have caused many to go astray, and those who have hoped in them have fallen away.
{34:8} The word of the law will be fulfilled without a lie, and wisdom will be made plain in the mouths of the faithful.
{34:9} He who has not been tested, what does he know? A man with much experience will consider many things. And whoever has learned much will explain with understanding.
{34:10} He who has no experience knows little. And he who has done many things has made many mistakes.
Sirach 34:1-5
{34:1} The hopes of a senseless man are empty and false; and dreams extol the imprudent.
{34:2} Like one who chases a shadow and pursues the wind, so also is one who pays attention to lying visions.
{34:3} In the vision of dreams, one thing represents another, as when a mask is before the face of a man.
{34:4} What can be cleansed by the unclean? And what truth can be spoken from a lie?
{34:5} Erroneous divinations and false signs and the dreams of evildoers are emptiness.
