This is an incident I had a few years ago when I was in Kanpur. The winter had just started and I preferred keeping my windows open so that fresh air can make my sleep more enchanting. I generally am in the habit of covering whole body from head to toe if its chilling outside.So there was I, sleeping soundly. There comes a time in the morning when although we are sleeping we unconsciously know that the morning has come and its time to wake up. So it was during this time that something hit my face with a bang. The sound of it was too loud for me to understand what was it. Although living alone generally I dont fear moving into my empty house even when it is dark, but this time it was different. I just laid there. The sheet was still covering my face but the hit was real nasty and I just couldn't comprehend what was it. Has the fan above me fallen down? No its so big, it cant be. Has one of the wings broken. No I can still feel the air of the fan. Two minutes gone then five minutes. I was really worried. Or is it my windows are open and may be some bird has accidentally got inside and got hit with the fan and now it lays their. oh shit! is it some crow? sparrow. Oh my! these thoughts ran fast through my mind.Then finally I took courage and very fast I lifted my blanket to really see the thing. Fear and curiosity both were ruling inside my mind by then. What was it ? Where is it? I couldnt locate anything. I got up and then walked a little to the window.
There it was lying just behind the door. Well Oh! its the folded newspaper with a tight rubber band on top. Now I got more curious. To my amazement the windows had iron bars and something can get inside only if it is thrown almost straight from outside but my flat was on the second floor and the newspaper vendor always has to throw it from below. Only this time he missed the target which till then was always my balcony. :)
Now I was getting more curious. I then did my own research. In the end I came to the conclusion that there's only one way that it can really enter through the bars. All the permutation and combinations pointed out that only when the object (in this case folded newspaper) is approx 45 degrees titled and also takes one more turn when half of it is already inside the bars of the window that the object can enter. It was a highly improbable thing and I was able replicate the action only after doing some hard work by really working it out.
Since then till I stayed in Kanpur I never covered my face while sleeping or whenever I did I took care that the windows are closed. :)
