I have a uv light pen and I was using it around my house and around midnight last night, then I saw huge green stains in the hallway on the carpet only visible with the pen, and every 2 feet there were more stains does anyone know what it could be? there was a green check mark stain too, I think it maybe stains from years ago that found its way into the carpet, or I could be the design of the wood under the carpet idk it’s kinda creepy btw happy Valentine’s Day
I took this photo at like 12 am XD
