גזלנו

                                                                               אשמנו בגדנו גזלנו     

One of the Vidui booklets in English who claims 

it's based on the Chayai Adam & Otzar Hatefilos

adds to the Vidui of גזלנו  "disturbing someone's 

sleep". 

I checked the Chayai Adam, Otzar Hatefilos &

Chida and none of them mention גזל שינה .

under  גזלנו

 גזל שינה (robbing sleep) is not mentioned

in Shas Bavli, Yerushalmi or any of the Poskim.

(pre Chofetz Chaim)

The first Mokor (source) is in the Sefer Chofetz Chaim.

R. Ch. Kaniyevski shlita said it has no connection to

Hilchos גזילה but a Musar concept of ואהבת לרעך.
