UFO or Enormous "Spider"? 500 Lights On Object0: Yes

I’m fairly certain the year was 1969 because I was about 3 years old when it happened. 
I was outside riding my tricycle by myself on the large patio at my apartment complex.  All I remember is this huge, round, light tan colored "thing."   It looked to me like a huge Daddy Long-Legged spider.  It covered the entire area of the patio - probably about 30-40 feet in diameter. 
Scared and not knowing what to think of it I ran inside.  
For years I thought this was just a weird dream, but I have always since (and still to this day) been terrified of Daddy Long-Legged spiders.  Having been so young and lacking sophisticated language I think I was unable to store this memory properly and so coded it as a huge spidery dream.
Witness indicates that the date of the incident is approximate.  PD
