scary thing in my life

Hi,
When i was in my 1oth grade iam going to school on my bike , it was windy and heavy rain .I have to go every day 4 miles from my village to near by town to reach my school , on the way i have to cross one bridge on river its about 1mile . when i started in my house it was moderate rain , after that it became heavy rain and wind . warning from local goverment was water level in river is too high and water is flowing above the bridge and its very dangerous to cross the bridge at that time , but i dint care that one and ready to cross the bridge , when i was on the bridge suddenly one heavy water wave came and throwed me into the river, i did swim 20 minutes after that its very difficult to swim. i thought it would be last day in my life iam going to die ,.
suddenly i saw large tree flowing on water came near by me and i catch that one and sat on that . its raining still and my tree is moving on water and struck with some big object. i saw lot of snakes, cattle, people were flowing on water i sat there like 28 hours and looking for help lot of dead bodies came and struck with tree where i sat , i affraid a lot and scary and sat one whole night with dead bodies near by me, next day after noon milatary people came there and lift me from there in to helicopter , iam one of the few people survived in heavy floods , hundreds of people died, it took almost one month for me to come in to normal life.
