I Saw My Roommate In Our Apartment, Then She Walked In The Front Door—And I Learned Her Dangerous Secret

I got home late from work, around 11 p.m. As I walked down the hall, I saw my roommate, Sloane, step out of the bathroom wrapped in a wet towel. She scurried into her room without making eye contact or saying a word, which was really strange for her. I just shrugged it off, assuming she was tired or in a bad mood, and went to the kitchen to grab a glass of water.

About five minutes later, the front door opened, and Sloane walked in, carrying a takeout bag. I stared at her, completely bewildered.
“What the…? I thought you were in your room. You literally just got out of the shower,” I said.

The color drained from her face. The takeout bag dropped from her hand, food spilling onto the floor.
“What did she look like?” she whispered, her eyes wide with pure terror. Before I could even process the question, she grabbed my arm, her grip like steel.
“Get your car keys. Now,” she hissed. “We’re leaving. We’ll go to your car, lock the doors, and call 911. Do not ask questions, just run!”

Huddled in my locked car a few minutes later, listening to her sob into the phone with the police, I finally learned the truth. That day, I was horrified to discover that she had a stalker, a dangerous one. A woman who befriended her a year ago and, little by little, started copying her. She thought she got rid of her when she moved but apparently, she hadn’t.

The police told us to drive to the station while a patrol car was sent to the apartment. Sloane was shaking so badly, I had to drive. She kept checking the rearview mirror like we were being followed.

At the station, we sat in a cold room while an officer took her statement. I learned bits and pieces—how the woman, named Cassidy, had become obsessed. She started dressing like Sloane, cutting her hair the same, even changing her voice to match. It had started off as flattery, Sloane said, until it turned into full-blown mimicry.

Cassidy had followed her from another city when Sloane tried to escape. She changed apartments, jobs, everything. She blocked Cassidy on everything and even got a restraining order. But Cassidy had slipped through the cracks.

The officer came back with a frown. “We searched the apartment. No one was there. But… your bathroom towel is still wet. And we found this.”

He held up a red scarf. Sloane gasped and clutched my arm.
“That’s mine,” she whispered. “I haven’t worn it in weeks. It was in a box under my bed.”

I was creeped out to my core. Whoever had been in our apartment wasn’t just impersonating her—they’d been going through her stuff. That meant she’d been inside for more than just a few minutes.

The police advised us not to return that night. We ended up crashing at a nearby motel, both of us too freaked out to sleep. I watched Sloane stare at the ceiling, eyes wide and unblinking. I’d never seen her so afraid.

The next morning, the detective handling the case called. They’d checked the building’s security footage. The woman entered around 10:40 p.m., just minutes before I arrived. She had a spare key.

Sloane looked pale.
“She must have copied mine somehow,” she whispered. “Back when we were still… when I thought she was just a weird but lonely friend.”

The footage showed Cassidy leaving the apartment just after I ran out with Sloane. She slipped out the back, wrapped in the same towel I’d seen earlier. It was all starting to make sense, in a terrifying kind of way.

We stayed at my parents’ house that weekend, far from the city. Sloane barely spoke. I tried to keep things light, but she was somewhere else entirely.

Then Monday morning came, and with it, something unexpected.

An email from Cassidy.
Subject line: “I WAS JUST TRYING TO BE HER.”
It wasn’t threatening. It read more like a diary. Pages and pages of rambling thoughts, talking about how she didn’t want to hurt Sloane—she just wanted to be her. She said she loved her, envied her, admired her. “You’re everything I ever wanted to be,” she wrote. “And I figured, if I became you, maybe I could be loved too.”

We sent the email straight to the detective. He said it helped build a case, but it also confirmed what they suspected—this wasn’t just obsession. It was a deep mental illness.

Cassidy was found two days later in a women’s shelter across town. She had dyed her hair to match Sloane’s and was introducing herself to people using her full name. When police arrived, she didn’t resist. She smiled and said, “I’m glad you found me. I didn’t want to keep hiding.”

It was a relief, but also deeply sad.

Over the next few months, Sloane started going to therapy. I did too, if I’m honest. The whole thing had rattled both of us. We changed the locks, added security cameras, and even got a big rescue dog named Scout.

But the scariest part wasn’t the break-in. It was knowing that someone could blur the line between admiration and obsession so completely. That someone could look at your life and decide it should be theirs.

One day, a package came to the apartment. No return address. Inside was a handmade photo album. The first page read: “Our life together.”

It was filled with pictures of Sloane—some from social media, some clearly taken without her knowing. Standing at a crosswalk. Getting coffee. Coming out of work. One even showed her inside the apartment, curled up on the couch.

That one hit me hardest. We hadn’t even noticed.

We brought the album to the police. They said Cassidy had violated her bail conditions and would now be sent to a psychiatric facility. She’d never mentioned a camera, which meant she’d probably hidden one in our apartment.

We searched every inch of the place. Eventually, behind the air vent in the living room, we found a tiny pinhole camera. She must have installed it months earlier. It had a small SD card inside.

I watched Sloane as she held the little black card in her hand. She didn’t cry. She didn’t scream. She just looked… resolved.

“I don’t want her to win,” she said softly. “I don’t want to be afraid anymore.”

She posted her story online, leaving out identifying details but telling everything else. The reactions flooded in—hundreds of women commenting, sharing their own stories of being stalked or manipulated. Some had never told anyone before.

One message stood out. It was from a woman in another state who said: “I think Cassidy did the same thing to me. I thought I was going crazy… thank you for sharing this. Now I know I wasn’t.”

That message sparked an investigation. Turns out, Cassidy had a history. She had followed at least two other women in different states. Each time, she’d worm her way in as a friend, then slowly start replacing them. But they hadn’t had enough proof, or they’d brushed it off as coincidence. Until now.

Sloane’s story helped open up multiple cold cases. One woman had even filed a missing person’s report, thinking Cassidy had disappeared. But no—she’d just reinvented herself somewhere else, each time leaving behind wreckage.

In a way, telling her story became Sloane’s healing. She started speaking at women’s groups and self-defense classes. Not out of fear, but strength.

One night, over tea, she looked at me and said, “You know what’s funny? I used to think I was just an ordinary person. Nothing special. But someone wanted to become me so badly, they lost themselves trying. I must’ve had something I never saw in myself.”

That stuck with me.

Sometimes, we don’t realize the strength or light we carry until someone else tries to take it. And sometimes, the scariest things lead us to the strongest parts of who we are.

Sloane still lives with me. We laugh a lot more these days. Scout barks at shadows sometimes, but he’s usually right. We don’t live in fear, but we stay aware.

The world can be strange. People can be stranger. But nothing is more powerful than choosing to stay true to yourself, even when someone else tries to steal that from you.

Have you ever felt like someone crossed a line with you—maybe in a way that didn’t seem dangerous at first, but slowly became too much?
