שמואל כי הוה חזי חלמא בישא אמר וחלמות השוא ידברו כי הוה חזי חלמא טבא אמר וכי החלומות השוא ידברו והכתיב בחלום אדבר בו
The Gemara relates: Shmuel, when he would see a bad dream, would say: “And the dreams speak falsely” (Zechariah 10:2). When he would see a good dream, he would say: And do dreams speak falsely? Isn’t it written: “I speak with him in a dream” (Numbers 12:6)?
§ The Gemara explains another verse in Proverbs: “If there is care in a man’s heart, let him quash it [yashḥena]” (Proverbs 12:25). Rabbi Ami and Rabbi Asi dispute the verse’s meaning. One said: He should forcefully push it [yasḥena] out of his mind. One who worries should banish his concerns from his thoughts. And one said: It means he should tell [yesiḥena] others his concerns, which will lower his anxiety.
A song of ascents.
When the LORD restores the fortunes of Zion
—we see it as in a dream-a—
