Unsettling. Discomforting. Unnerving. Disturbing. a few words I'd choose to describe your work here. Those are compliments, you did a very good job at making a psychological horror sound track.
However, and maybe it's just me, this was literally painful to listen to. Especially the high pitch noise in "Come Back" I thought that I had my volume too high, until I realized it was already halfway down. That note was LOUD. You have a great assortment of sounds and effects and rhythm, and for that I think these are great tracks, but mixing is especially important when your dealing with extreme pitches and shifts , like you were.
Great work outside of that.
