Night into Day

In June or July of 1985, my sister, me and our mom were waiting for a bus around 5:30-6AM, it was still very dark outside.  We were living on a farm in Poland (near Dzierzoniów) so i remember hearing roosters very vividly.  Suddenly, all went silent and night turned into day for several seconds.  I remember looking around and when the light disappeared, the sun was starting to come up so it was no longer dark like it was what seemed like just seconds earlier.  I tried to say something to my mom and sister but they seemed dazed, although I felt completely aware and oddly at peace with what just occured.  Over the years I tried to bring up the subject but my mom would avoid answering.  Until last year, I decided to ask again and both my mom and sister confirmed that it happenend, that they remember but both seem frightened, where as I am not.  Obviously I am curious if anyone else has experianced something like this.  Something tells me it was more then just a sighting as that was not the first time I experienced missing time nor was it the last.
Witness indicates that the date of the sighting is approximate.  PD
