Guest called the cops because of “scary noise”

So I host a cabin in the woods in the Catskills mountains NY. Last night my guest sent a message saying she heard a noise that sounded like someone knocking on the door, so instead of just looking out of a window to see if anyone was there, she called the cops! I watched two police cars turn up and the police do a sweep of the outside of the house from the doorbell camera. There was no one around. The guest said she heard the noise a few times even after the cops left. I checked the doorbell camera again and saw some large moths flying around, could they have been flying into the window making the sound? I’m sure the guest must have been high too. Seem like such a waste of police time, hopefully there is no repercussions to my property for this. Has anyone else encountered guests calling the police for a ridiculous reason?
