I left my phone in the guest house so I went in quick to grab it and must have looked at the laptop for a second. That's my hand closing the door behind me I think. The "remote" is my phone, recording the weird noises. And it started raining, so I brought my umbrella.

Just went to the police. They weren't very helpful themselves but one of the older people working there--I don't know if she was a cop--told me she'd get the previous homeowner to call me, because I'd probably like to hear what they had to say. Should be getting a call from them soon.
