A sound of blowing on a glass bottle..
So this has happened to me and my friend twice already. The first time it happened I was just chatting with my friend on a sort of a beach but not kinda. And this happened in the evening/night (when it’s dark out). So we were just chatting there and we we’re interrupted by this sound as if somebody blew on a glass bottle but it was way louder so we could both hear it clearly and the sound was repeating for a while so then we decided to leave. And this sound was like everywhere we heard it all around us and we were there on our own there was nobody else no where near us. So fast forward to today we went to the same place like usual and we were just chatting about something again and then we were interrupted by the same sound again at the same place! I realised just now writing this that I should’ve recorded it this time but we just got so spooked by it that we left immediately. I just neeeed to know if this is paranormal or if somebody else has heard anything like that..
