Well, either call a plumber, or sit DOWN when you pee

maybe time to install a camera to check what's going on

I definitely have questions, but I'm not sure I'm mentally or emotionally prepared for the answers.

Maybe you slept walked?

Are you on Ambien?

There are only 3 possible explanations. 1. Your toilet is leaking. However, that is unlikely or you'd have been cleaning puddles on a daily basis. 2. You're not as alone as you think you are. Again, that is unlikely. 3. You are cleaning your own pee that you don't remember leaving. Although it seems silly, it is the most reasonable explanation. Maybe you should install a camera?

Either you sleep walking, someone has been coming to your house that you don't know about, or your house is haunted..

Okay one of two reasons why this is happening: you have a poltergeist, or you drink a just don't remember peeing on the floor. And since the simplest solution is usually the correct answer, I'm going with the poltergeist lol.

Maybe a rodent or animal of some kind you don’t know about?

Time to get those pee pee pads and not the kind for dogs.
