I once lived in an older house, approx 100 years old, that had been made into 2 apartments. I lived in the upper 2 floors. The 2nd floor was the main living area with a living room, a large kitchen, 1 full and 1 half bath and 2 bedrooms. There was a door between the main bedroom and living room that led to an attic room on the 3rd floor that had been converted into a large open room. The stairs bisected the room, to the right was my bedroom, to the left I had set up as a sitting room. The stairs leading up to the room were included in the room-my bedroom door was at the foot of the stairs. I had quite a few odd experiences in the time I lived there but this was one of the most memorable.
One night, I had gone up to my room to read before bedtime. I read for about an hour, then turned out the bedside lamp, snuggled in to sleep. At about the same time, I heard the door to my room open. The 3rd step from the bottom creaked when you stepped on it and I heard that too. I was lying on my left side which means the stairs were behind me. I had 2 roommates at the time. If I received a phone call after I went up to bed, 1 girl would ask the caller if they needed them to disturb me and if not, she would just take a message, the other girl would just come into my room. Both would come about halfway up the stairs, then whisper my name. If it was the first girl, I'd answer if I were awake, the second I wouldn't just because I didn't necessarily want to be bothered for a phone call that wasn't important. I laid there waiting for one of them to say my name but no one did. A little alarmed, I rolled over to see who had come into my room. At the top of the stairs there stood a young boy. He was facing forward, so facing the wall and I was looking at his right side. He had dark hair with a pageboy type haircut, a dark, short jacket (brown, I think), pants that ended just below his knee, light colored stockings with ankle boots. I was shocked and sat up on the side of the bed and asked out loud... How did you get in my room? He slowly turned his head and looked at me, then just... Twinkled out. The only thing I can compare it to was it was like a sparkler. He just twinkled then disappeared.
My mind was reeling and all I could think was to get downstairs to my roommates. I ran so fast down the stairs that I stumbled as I turned the doorknob and fell out the door into the living room floor. Both roomies were watching tv and I asked them how they did that. They asked what did we do, and I said... How did you get that boy in and out of my room like that? One went to get me a glass of water, the other had me sit down on the couch and I told them what had just happened. They denied that anyone had opened my door or gone up my stairs and told me I was just dreaming but I had not been asleep, so I know I wasn't dreaming.
I never saw the boy again but had many more experiences in that house. I had friends who thought I was nuts to stay there but it never felt threatening, I just felt like I was just sharing their space with them.
