Saw what appeared to be a meteor at first, but discovered differenty.

Well it was holloween and me and my buddy had just got done trick or treating in my neighborhood and was about to head to another one. we were heading west on gregory st, and about 30 feet from n. dettman. When suddenly something caught my attention out of the south (my left hand side). i said "hey look a meteor". me friend and i stopped to watch it, it streaked in the sky for about 2 seconds if even that when all the sudden it stopped. It changed about 3 different colors started out as white, changed into red, green , then a blue color. at that time i looked at my friend and said "what the hell is that"! Then all the sudden the sky lite up like lightning does, and it was gone. my friend started crying and told me he wanted to get the hell out of there , but i managed to calm him down. But at the same time i was shaking very nervously. I still don't know what that was exactly,i know it definetly wansn't a meteor or any kind of plane. i just wish that i had a camera on me that day.
Witness indicates that date of incident is approximate, although he indicates the correct date for Halloween.  PD
