求翻译：你打电话是11点，虽然11点和11点半之间只有三十分钟，但是11点的时候我确实就是在睡梦之中，电话一点声音都没有，我怎么可能听见？妹妹打电话也没有声音，是因为我正好11点半醒了所以看见妹妹打电话是什么意思？

You call is 11 points, although only 30 minutes between 11 and 11:30, but 11 points when I do is dream, the telephone without a sound, how could I be heard? Sister called has no sound, is because I was half awake so 11 points to see sister called
