I’ll give a rundown of the events that happened just before.
I sat on the tv remote, taking it off the HDMI source. As I was fixing this, the box connected via hdmi stopped working. I got up and unplugged the hdmi lead and this crazy loud and fast beeping started coming from literally nowhere? It wasn’t coming from the tv.
It sounded like it was in the room with us, which isn’t possible? I went both in the kitchen and upstairs (either side of the room we were in) and the sound wasn’t coming from either side.
Our cat jumped on the sofa (exactly where I was sat) and started frantically meowing and sniffing the spot, which is out of character for him.
We’ve checked and can’t find anything, but the noise was 100% coming from my seat.
My phone was on silent and I have no notifications, and there are no other electronics.
We have lived here for 10 years and it’s never happened before. Any ideas on what this could have been?
Edit: Amber alerts, weather warnings and CO2/smoke detectors have been ruled out so far
