Apparitional Experiences Part 3

The top landing of the hallway has a window, and across from it is a door that leads to the attic. On each side of them, there is one door, each leading into a bedroom. The boring, front bedroom is to the right, and what appears to be the master bedroom to the left. The master has a full bathroom, but no shower head. It also has a larger closet, with another closet inside of it. Yeah, we never understood that either. I may have written this before, but when my parents first moved in there, that was where they had their bedroom. My father often worked second or third shift, so my mother had no problem with having her kids in the bed with her until they were grown. The room has reports of dark shadows, something walking across the floor, something bumping into the bed, and the door to the closet opening by itself. Sometimes you could hear the door handles slowly turn in the adjacent room, when you had the door locked on the other side. Currently, the drywall caved in due to rain damage from a leaking roof, so while the roof has been repaired, no one uses that room since it hasn't been fully repaired. That's sad, really, because it's the same size as the living room, and only limited by the additional bathroom and closet.
When we asked the previous resident, one of Gertrude's younger sisters, about deaths in the house, the response was a brief silence, followed by a confirmation and question as to why. Feeling like an ass, my mother moved along and just said she was curious. They then told us how the downstairs bathroom used to be a walk in closet, but that after their sister died, the kids didn't like going into the master bedroom, so they added the bathroom downstairs. As the family grew, they added on a kitchen/dining room and another room to the basement, but the master bedroom went largely unchanged. Aside from the little girl footprint, we never saw anything resembling a little girl. Then one night my nephew, maybe 3 or 4 at the time, was supposed to be asleep but came into my sister's bedroom and told her that there was a girl lying on the floor in a white dress. He thought it was his sister, who was around 9 at the time, but then she turned and looked at him and he realized it wasn't her. I know, children aren't the most reliable witnesses, but it was a rather odd coincidence. Add that to the body of reports that sound like someone sneaking through the house, and it starts to make you question. I looked into the event as best I could.
I gathered that Gertrude was born in 1908, and I believe she died nine years later of scarlet fever, in the house. She may have been the oldest daughter, but I'm not absolutely certain. I can't remember off hand how many siblings there were total. With most of the activity stemming from the master bedroom, it makes me wonder if that was the room she died in, separated from her other siblings.
