I have a security camera indoors. If I'm away, I might have a quick peak, to make sure all's ok. When the infrared light is on, I can see hundreds of pinprick particles flying through the air in the living room. Not dust and not i bloody well hope bugs. What the hell can it be? Weirdly though, a friend was round yesterday evening and she said she kept thinking she was seeing stuff flying around 🙁 I hadn't told her about camera, so I can't have planted the idea in her head. It's a perfectly normal house, super clean, defo no obvious flying shit in the air!
