“I was living in an apartment with 3 roommates at the time. I was working all sorts of weird hours, and would stay up late most nights. Our apartment had 2 hallways that formed an capital L. My room as at the "top" of the L, the bathroom was in the corner of where the lines meet. With the door being in the inside middle of the small section. In the outside corner was the living room.
I walked out of my room to go to the bathroom, no need to turn the light on as this was a trek I had made hundreds of times before. As I left the bathroom I turned to go back to my room. Just as I turned off the lights of the bathroom there standing where the short hallway and the living room met there was a teenage girl standing there. Wearing a white flowery dress, just smiling. She didn't look "evil" just a normal person standing there smiling at me. I freaked the fuck out and went running for my room.
About 20 minutes later I finally came out of my room. Turning all the lights on as I went through the apartment. She was no where to be seen, however where I saw her standing was noticeably colder than the rest of the apartment should have been for an August evening. Creepy, but not the worst part.
I lived there for about another year, and I never saw her again. After I had moved out I was hanging out with my one roommate who had the bedroom at the end of the small hallway, right next to the bathroom. We were talking and I told him that I never felt comfortable in the apartment after something happened. To which he responded "Oh, you saw her too" I nearly drove off the road when I heard this.
We then both described her, finishing off each others sentences describing her. He had seen her twice. I was indifferent about ghosts before that. Now I believe in them..or believe in something. It was very creepy and every time I tell the story the hairs stand up on my arms.”
