Someone on the Other Side of the Door

I am writing this on behalf of my 18 year old sister as she doesn't feel comfortable joining the site. It is only because I told her my story and where she could read it that she has come forward with her own experience.

About 3 week ago she was home alone at 2pm in her bedroom watching television with the bedroom door closed. She heard creaking on the landing floorboards at the same time as the front door sounding as though it was being opened then closed. The door has a very distinct sound, although no sound was heard on the stairs. She walked out of the bedroom to look at the bottom of the stairs (the front door is opposite the staircase) to see if it was me and my kids coming to visit (as apart from her, my mum, and my step dad I am the only one with a front door key) nobody was at the bottom of the stairs as nobody had come in. She then went back into the bedroom and still heard the creaking on the landing floorboards. This continued every few days for the next fortnight, the door however was only heard 3 more times.

Last week when she was in her room again with the door closed, she stood up to leave to go downstairs. As she approached the bedroom door she suddenly had an intense feeling that there was someone else on the other side of the door, she froze, sat on her bed and didn't leave the room for an hour! When she got the courage to open the door there was nobody there, as the feeling had left. There were always rumours about our parents house when we first moved in, about a boy in his bedroom either dying or committing suicide. We never listened though.

Now she gets feelings on most doors upstairs that there is someone on the other side of the door, or in her bedroom she thinks someone is in her doorway. She does have a belief in the after life, ghosts etc, she would just like to know other peoples thoughts on this.
