Sleep on Friday Afternoon

Friday afternoon is a time of sleep above. Great Chassidim would go to sleep at this time. The purpose of sleep is for the soul to go up above and draw more life in order to study Torah better. This is true about the sleep of every night, and even more regarding the sleep before Shabbos, befitting the higher level of Torah study on Shabbos.
