some of আপনি have been asking after the dolphins so i looked it up and finally found them, i know it's not very good but hopefully আপনি can see it now(unless your really corupt lol)
আপনি don't nessasarily need to watch this all the way though but on pause it at 4:46 a floating shadow can be seen 5:09 a man/figure can be clearly seen when the camera goes back a mere সেকেন্ড later the man/firgure is gone
