Swaying round light at rooftop height between 2 houses and right above--a huge triangular black object--no sound.

In my vehicle was myself and my 3 sons--all under 14 years of age at the time.   I was driving along and I looked to the side because this light caught my eye--I stopped.  This light didn’t have a beam and it was swaying back and forth between two houses right at rooftop  height.  I looked up above to see where the light was coming from and it was a huge triangular shaped object in the sky.  This round light started to come towards my car--everything around us seemed gray and quiet and no sound--it felt like time standing still..  I have always heard of missing time and I glanced at the time on the car.  I went out right at that time and when I came to I looked at the clock and I was missing one hour.  I asked my kids if I had fallen asleep and they said no--they said we hadn’t been there very long.  I asked them if they had seen the light and they said no.  I didn’t realize there was a place to vent like this and I’m glad I can finally say something.
