Do you want to go to sleep? This is not a common expression in Korea and its usage could be various. For eg. if you say that a chick that you just bumped yes it could be "wanna f*ck" or something like that but if you say that your children or friends it means "do you want to go to bed" or so. Anyway, "Jaro gal-lae" can be translated "Do you want to go to sleep". "with me" don't need be there unless you say "narang jaro gal-lae".
