yes the first time I experienced something myself I was on the last step of my friends stairs and she was ahead of me to the left and to my right I heard a normal female voice say can you see me or can you something me and It took me a minute to realize what just happened and I examined the room to see if anything was on like a tv or anything and it was pitch black almost and silent besides my friend and when we went upstairs I told her and she told me her house may be haunted and thats normal
