It was just my father and I in the house one evening and we both had to use the restroom. So, I went upstairs while he stayed on the first floor, and I left the bathroom door open because it was just us. While I was sitting there though, I could hear this odd swishing sound, and knowing my father likes to wear athletic pants, I thought he was done and walking around. But then I heard him flush downstairs an instant later. Slightly confused, I left the bathroom, walked into the hall and looked into my bedroom, where this pillow, made of swishy material, was sitting meticulously placed at the edge of my doorway. It wasn't near anything it could have fallen from... and that noise was way to close to have been anything else... I remember the hairs on my neck standing up, and I went downstairs as quickly as I could.

Same presence as on my bed several years before? Who knows...
