This happened to me during my first year of university, in October. I was living in the dorms and I need to give you a brief run-down of the dorms - you need a keycard to gain access to your specific floor, so even though someone on the 3rd floor and 4th floor live in the same building, they can't access each other's floors.
I had injured myself playing sports, so I was under orders to 'rest', which meant no Hallowe'en parties for me. Pretty sad for a horror fiend like myself, but to try and make the time a happy one, I busied myself helping to make costumes for people and doing their makeup. Once I was finally finished, I packed up my makeup and decided to watch some movies in my room. A guy popped up and introduced himself, we chatted a bit and exchanged email addresses and I walked back to my room and said goodnight. The first warning sign was that he walked into my room behind me, despite me saying I was going to walk into my room. I felt really awkward and tried to say, in a roundabout way that he needed to leave. But he wasn't getting the hint. I finally had to say 'you need to leave my room now.' I chalked this up to him maybe being drunk or something, but I did wonder how he got onto my floor if he wasn't with anyone partying. Before I went to bed that night, I checked my email and there were 5 from Creep. The first being 'hey I'm so glad we're friends' and the rest asking why I wasn't online.
A few days later, I got a knock on my door when I was studying and it was him. I explained that I was studying and needed privacy. He tried to walk into my room again, but I braced my arm on the frame and said firmly that I needed to study. The next day, he was at my door again and the next. I began pretending that I was not home. Another day there was a knock at the door and when I checked the peephole, there was no one there and I assumed the postman had come. I opened the door and lo and behold, it was the creepy guy. He has begun hiding from the peephole so I would be more likely to answer the door. I told my roommate never to open the door if he was there and I told the people living on my floor that this guy was beginning to creep me out, so if he wanted to get on the floor, whatever sob story he gave them, don't let him on.
