Incident on Pacific Coast Highway leads to time loss

My first husband and I were on Pacific Coast Highway taking a late night drive.   It was a week night, but neither of us had to work the next day so we caught a late movie and went for a drive.    We were on PCH directly in front of the Pier.   Everything on the pier was closed and there was no one else in sight.   Suddenly, an object appeared out of nowhere and began hovering over our vehicle.  There were several lights coming from the object that alternated between yellow, green, and red.  The object followed us down PCH.  The next thing we remember, we were on the 605 freeway heading towards Los Angeles, and it was a little after 3:00 a.m.   We are now divorced, but neither one of us ever spoke of this matter again.   I have had 3 other sitings:  1967, 1987, and 1997.  I feel there is some significance to the 10 year intervals.  I seldom speak of these incidents because family and friends don't believe me.  They think I was either dreaming or just saw an airplane.
The date of the incident is approximate.  PD
