My girlfriend said something weird.

So, I (25F) and my girlfriend (24F) are at home together, and she’s just been acting really weird.<br><br>She was sitting on the couch, watching TV, and suddenly she just got up and walked away.<br><br>I was a bit surprised and asked her what was wrong.<br><br>She looked really confused and said, “I don’t know what you’re talking about. Why are you asking?”<br><br>I explained that she was watching TV and then got up, but she just looked at me weirdly and said, “No, I wasn’t watching TV, you’re watching TV.”<br><br>I thought maybe I had hallucinated it or something, but she’s still acting really weird.<br><br>She’s been acting really distant and has been asking weird questions, like if I was “a robot” or “a digital being” or something.<br><br>I’ve tried to explain to her that I’m a person, but she just looks at me weirdly and doesn’t seem to understand.<br><br>I’ve been trying to reassure her that everything is okay, but I can’t shake the feeling that something is off.<br><br>Has anyone else experienced anything like this? Any ideas what might be going on?
