Why is the briss held on the eight day?

When I was about 10 years old I was liveing in a foster home. And I was haveing a realy tough time with just about everything. One night I woke up and saw someone or something standing at the side of my bed. I could'nt see a face or body it was like a glowing light in the form of a man...He reached out his hand and said to me "Angel come with us". And he just flew up out of the room and was gone..Now I was very sceard because nothing like this has ever happend to me before. So I did'nt want to back to sleep. ut I would saw about 5 seconds later I was sleeping. This was the first and only time anything like this has happend to me..Soe people saw it was an "Angel" other people say it was a "Wakeing dream" Can you help me with an answer?.Thankyou.

Dear Rabbi, Is the shaking of the lulav permitted on Sukkot during the night, or [like the tallit] is it a daytime halachic mandate?

Dear Rabbi Moshe Newman, You asked me to go to Jerusalem to fulfill my wish but will you please tell me How can I? Our country Bangladesh don't have any diplometic relationship with Israel. So How can I reach there? By the way If I can go there who would arrange my living? Will I get a job there? I am M.Com (Accounting) & MBA. Will the people of Jerusalem except me, If I become a Jew? Thank You Shamim
