I Was Haunted By The Old Hag Ghost

This is from my last apartment. My cat had been acting very strangely and I had been feeling a strange presence as well. I grabbed my iPhone and recorded on a whim and it wasn't until AFTER I recorded that I noticed all the strange things I had captured. Most disturbing is what I came to call the "Old Hag" in the window. This was the first time I saw her. She had wild white hair, flowing like she was underwater. Black holes where her eyes should be and a big black open grimacing mouth. I lived on the second floor so I have no idea how she could've been looking in my window like that. Also, when I swung the camera back, she is gone. In addition, there is a bizarre inverse white "shadow" in the bathtub the shape of a woman that moved. It was there for a few days and it would move as I watched it. I was terrified and sent this video and a couple others to a paranormal expert who debunks such things for a living. He said he couldn't be positive but he felt these were signs I was being haunted. So did a paranormal psychologist I consulted. Needless to say, I moved.
