Encounter With Some Super Natural

 That morning i was going to school .It was a cold winter day and little fuggy.My School was about 45 minutes from my home and i had to walk at least 20 minutes along a brook which was little bushy.

         A  little boy holding a long stripe bag made by local tailer was walking with great excitement. Suddenly I stoppend in the middle of the Creek and tried to move little back but my legs didn’t move .My legs  were trembling and tried looked both sides but I couldn’t move my eyes from that objects .That object was slowly doing back and forth .I wait for anothe 20 minutes then one person came with his bull ,he was going to plough his field .I followed him but i didn’t tell him any thing .That time i found the moving object was just a old plastic sack.I still remember that event .
