My wife has been peeking at me from around corners and behind furniture. It's gone from weird to terrifying

Our first year of marriage was a dream. Literally, dream come true. I had met my now wife, Sarah, at a coffee shop I frequent for work. I couldn't believe that someone so beautiful was actually interested in me. It was crazy. I'm not trying to sound like some loser who can't get a date, but I was a little that way before I met Sarah. To make matters worse, she seemed to be lacking any/ all flaws. Pretty, intelligent, nice, fun, caring, a good cook, takes care of herself, loves to have sex, well humored, and the list just goes on. <br><br>After moving in together and getting married, things just got better. It was all so perfect, as cliché as that is. It was truly what I consider a dream come true. And that brings us to our issue. <br><br>About 4 months ago, I started catching glimpses of Sarah peeking at me from around corners or from behind furniture. At first I didn't think much of it. I assumed she was just playing around or trying to be silly, as she is prone to doing. Then, on multiple occasions, I started catching her staring at me. I would be watching TV on the couch and catch her looking. Her face would light up with a smile when she noticed me looking back and she would say things like "Eww. I was just trying to stare at you" and "I love you dummy. Leave me alone." <br><br>I started to not really notice her doing it, because I was used to it. I honestly kind of liked that she wanted to look at me so bad. It was flattering, and I loved her so much. But then she started playing hide and seek with me. Then she started hiding and "scaring" me (she's not scary though, so it's just like a little startle and laugh). Then she was hiding and just watching me (she admitted this one to me). Then it was all of the above and worse. <br><br>She started hiding more and more, and it was getting kind of scary. One night we were going to bed and I caught her hiding behind the door. She had a creepy grin on her face and a twinkle in her eye. She hopped out and said "Gotcha!" in a playful voice and we laughed. But I noticed something when she jumped out. When she was hiding, her eyes were closed like she was bracing for something. When she jumped out, it took her a second to remember how to react. I've seen that look in a persons eyes before, and it's the same look that people have when they're on meth. <br><br>I work with a lot of drug addict, (homeless, alcoholic, and mentally ill folks) so I know that look when I see it. But Sarah doesn't do any drugs at all. I thought about it for a while, and I decided that it was probably just a weird fluke thing that doesn't mean anything. I thought that if I ever caught that look again, I would confront her. But I really didn't think about it much. She was still the kindest and most loving person I've ever met. <br><br>I love her more than air, (thats how much right?) and honestly, even if she was Scary Michelle from the meth house, I couldn't stop myself from being devoted to her. But I still looked for that weird look. I didn't find it again until last night.<br><br>It was around 11:00 and I was heading to the kitchen to make some food. It was dark in the apartment, except for the light above the stove in the kitchen. As I was making my food, I noticed something peeking around the corner of the hallway in my peripheral. I looked over and didn't see anything. This happened about three times, until I stopped to get a better look. I finally saw Sarah peeking at me. I said hi, but she didn't respond. She just looked frozen. <br><br>I couldn't see her face very well, because it was dark, but I noticed something. Her eyes were closed. Like she was bracing for something. I stopped looking and started making my food again, thinking she would come out when she felt comfortable. But after a minute, she was still peeking. <br><br>I decided I wanted to go to bed, I was a little spooked out to be honest. I walked towards the hallway, and when I got closer to her she backed up into the darkness. I called out to her, saying "Sarah, what are you doing? It's late." There was no response, and it was starting to get really creepy. I crept down the hallway and called out again. "Sarah its late. Get out here so we can go to bed." <br><br>I heard rustling, and then Sarah slowly started to come into view, but she looked different. Her eyes looked wide and scary, her mouth was saying something that looked like "OOO" and she was walking stiffly. She kind of reminded me of a zombie, from the waist up. Her head and upper torso were all I could see. It was one of the scariest things I've ever seen, honestly. I shook my head a bit, figuring it was just the sleep deprivation. <br><br>She got closer and I looked into her eyes. I saw it again, the meth-look. She looked at me and said "Gotcha!" But it wasn't the same tone as before. Before, it was all bubbly and fun. This was more like "Gotcha now you're dead, sucka!" It sent chills down my spine. I grabbed her, and she kind of twitched. I said "Sarah, what's going on? Why are you hiding so much?" Her smile turned into a frown. She looked like a dog that had just done something bad, and she moped her head and shoulders down. <br><br>I asked her again, (we were both in the hallway, both of us frozen in place. My arm was on her). She looked up at me with big eyes, not like they were dilated big, but sad big. Her eyes said "I'm sorry," and I thought she was about to explain herself, but instead she said, in a monotone voice, "I've been hiding because I love you." She then turned and walked towards the bedroom. <br><br>I followed, and she just got into bed, watching TV. I got into bed too. She offered to give me a hug, and I took it. I asked her if she could promise me that she would stop playing hide and seek, because "babe, it kind of creeps me out." She squeezed me with all her might and when she let go, she said "I promise." Then she smiled. <br><br>It was really scary, but she looks just like an angel when she smiles. I'm trying to forget what happened, I think it's just anxiety that's making her act strange. Maybe she's afraid of something, and she won't tell me. I know she's not on drugs, I would see some sign. And she's definitely not a zombie or demon or something. I'm probably just being paranoid. This is what I keep telling myself. <br><br>But I'm worried. And I want advice. Has anyone experienced anything like this? What the hell is wrong with my beautiful wife?
