I swear I've been seeing stuff lately. I must be going crazy. 😳 like I swear I see something run across the room or someone sitting in my back seat in my rear view mirror but as soon as I look, nothing is there. I'm wondering if it's anxiety because I'm hyper-alert to noises all of a sudden too. I swear it sounds like someone is walking around downstairs and I'll lock myself in my room upstairs until I can calm down enough to convince myself nobody is down there.
