I saw a hazy blue ball of light about four feet in diameter just off the ground.

I was waked up one night by my dog barking and could hear every dog in the neighborhood barking.  I finally got up to take a look outside and saw a beautiful blue ball of light just above the ground in my yard.   It didn’t have a definite shape, just a soft glow of light.  
I saw it for only about four or five seconds but that was long enough then it just disappeared.   My little dog was with me and we went back inside and went to bed but I didn’t sleep much that night.  
The next day I called the television stations to see if anything had been reported but they said no and I wouldn’t give them my name.  I’ve only told a few people about this because it makes no sense.  
I lived in the country where there weren’t any lights so it couldn’t have been any kind of reflection.  
The next morning I went out to look at the place where the blue ball had been and my little dog ran over to sniff the ground.  I wasn’t dreaming and I don’t drink.  This has puzzled me for many years.
Witness indicates that date of the sighting is approximate.  We have assigned an arbitrary date.  PD
