After exiting a Fred Meyers store. I noticed a disk shape with slightly slanted sides that had rectangular shapes that changed colors. I believe reddish, orange and a bright greenish yellow mix color. It was hovering approximately 1500 feet away from me over homes in our suburban area and was approximately 600 feet above. I remember it having a low pulsing hum sound. I ran home and told my mother whom didn't believe me but my insistent begging made her leave and walk down 2 blocks to see for herself. I seemed like she was gone for 2 hours as I waited at home as she instructed me to do. When she returned she simply said it was nothing! Coincidence or not but around the same time she was diagnosed with schizophrenia caused by hormonal changes. As I think back to that 2 hour time frame, I remember looking out the front door and all I recall is seeing a haze that was sunlit I guess you would say and no vision of even seeing the neighbors homes or the street!
