I'm still here

I came home pretty late one night and my roommates bedroom was shut and I assumed she was sleeping already but I saw something out of the corner of my eye in the kitchen, I said her name but she didn’t answer. I didn’t think anything of it so I walked into my room and before I turn the light on something whispered “I’m still here.” I turned on the light in my room but nothing was there so I turned on every light in my house and knocked on my roommate’s door and eventually opened it but she wasn’t there so I left her light on too and slept with all the lights on. When she came back the next morning I asked her if she was messing with me and she started crying and said she left because something was in the house messing with her and she had to get out.
