fiery yellow-white orb hovered just above the ground in back yard of home just west of I-15 in Provo, Utah

I have never been sure if this was just a dream, as it doesn't seem possible that it could have happened.  However, I have always had a lingering, unexplained fear of the area where it occurred.  Things have gotten rather muddled over the years, but the elements I distinctly remember are standing in the back yard with my mother at about age 2 years old, while an fiery yellow- white orb, about 10 feet in diameter, came down and hovered about 2 or 3 feet off the ground in front of us. After a little while, it flew away in a kind of wavy motion toward the southeast.  I also seem to remember laying in bed afterwards while my mom spoke to a policeman at the front door.  I'm not sure how this could have actually happened. I am sure my mother does not remember it.  Our neighbors would have had to have seen such a thing. And I doubt very much whether a police report of the incident exists. All the same, I have always been afraid to go in our back yard at night. When I was about 6, we added a family room onto the back of the house, and the area it was built on was the same area where the event occurred. I have always felt very nervous going into that room at night. Still, I don't think I "remembered" the details of this event until I was about 11 or so and started hearing about UFOs, so it may be some kind of false memory. I honestly don't know. But I thought I'd report it anyway, just in case. I have never heard of a UFO quite like this one.
