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.
