“I know the gemara talks about it, does anyone know where and what it symbolizes?”
Berachoth 56a – talking about an evil dream interpreter, Bar Hedya:
Subsequently Raba went to him by himself and said to him: I dreamt that the outer door fell. He said to him: Your wife will die. He said to him: I dreamt that my front and back teeth fell out. He said to him: Your sons and your daughters will die. He said: I saw two pigeons flying. He replied: You will divorce two wives. He said to him: I saw two turnip-tops. He replied: You will receive two blows with a cudgel. On that day Raba went and sat all day in the Beth ha-Midrash. He found two blind men quarreling with one another. Raba went to separate them and they gave him two blows. They wanted to give him another blow but he said, Enough! I saw in my dream only two.
Finally Raba went and gave him a fee….[and from then Bar Hedya gave good interpretations]
The first thing to ask is were you thinking about dental work any time recently? If yes, then the dream came from you own imagination.
If no, we have to see if came from a mazik or from a malach.
When did you have that dream? Which Hebrew day and date? What time of night? Are you in E”Y? Did you say kriat Sh’ma (to protect from mazikim) – at least the first two lines or at least saying “biyadecha afkid…”? Did you wake before the dream (that ends your protection unless you say it again)?
How real did it feel in the dream?
I have a book about dream interpretation by Rav Sh’lomo Almoli at home. Tell me more details and I can see what it says.
