I woke up at 3AM to give my doughter her bottle. I heard these strange noises which sounded very much like the ones that have been going around.
…this is not fake. My only dount is the fact that there IS construction near us for a new neighborhood. But I never heard these sounds before (or after) and why would they be working at 3AM?? This IS after me “stepping outside” – to my balcony. Although other buildings are in the way so I can’t see much
