Strange noises in Bucharest

Pretty lo-fi recording of strange sounds in Bucharest. The noises started at around 1 AM and kept going for half an hour. As they grew louder, the light in front of the house went crazy and eventually turned itself off. Right after that, you can hear several other noises that seem not to come from the sky, but from relatively close. That's when i freaked out, stopped the camera and ran inside.
