This story took place about four or five years ago, and to this day I still can not look at the windows in my mom's apartment at night.
My mom lives down in Seaside, California. It is about an eight-hour drive from where I currently live. I usually go to visit her during my time off from school. This time I decided to take my older step-sister with me. We arrived in Seaside at about 8:00 PM. We greeted my mom and got comfortable on the couch with something to eat.
The living room of her apartment is pretty small. It is set up so that the couch is against the wall, and across from this wall is the television and a rather large window.
My step-sister and I were happily watching the television when suddenly I saw this girl (or young woman I guess you could say) float across the window and into the television. It was probably from about the end of her neck up to the top of her head, she had long, wavy, and what looked like would have been blonde hair, and fair skin. She wasn't wearing any set expression on her face and she looked pretty tranquil as she drifted across the window. At this point in time my heart was in my throat and I convinced myself not to say anything to my step-sister and in doing so, I would forget all about it, but before I could think another word on it, my step-sister blurted out, "Bailey, I just saw a ghost, a girl ghost". I said I had seen the same thing.
It was reassuring to know that I wasn't the only one who had seen it, but it was also really frightening to know that there was a ghost in my mom's apartment.
I am positive that this wasn't someone walking by the window because my mom lives on the second story, unless someone was inside the house with a projector, it wasn't a hologram.
I have not seen the girl's head again, or any other ghostly experiences since then.
