These weird sounds were recorded in Chicago, Illinois, USA on the 2nd october 2012 at exactly 4:50 am. Thes Strange Sounds were experienced in the broadway and foster area of chicago. The Humming sounded slightly distant, like monks chanting over and over. Her friend also heard the sounds but in contrast to the recorder he thinks the sounds are from a construction site (construction of the CTA rail in the area). I believe that we have here another videos about the strange sounds in the sky phenomenon which is presently gaining in power and strangth.
What do you think?
