The night corresponds to Olam haZeh; the day which follows it to Olam haBa. The three watches of the night are divided as follows: first watch was Bayis Rishon which was destroyed through bitel Torah which is represented by a braying donkey; second watch was Bayis Sheni destroyed through loshon horo, represented by howling dog; third watch will be Bayis Shlishi represented both by infant suckling (Klal Yisrael imbibing Torah from HKBH) and a wife (Klal Yisrael) talking with her husband (HKBH).
