/x/ - Paranormal / Occult

Recently, my friend just got into therapy. And has been speaking to her therapist about her old home. All you need to know is that she had past traumas there and her mother apparently had, "attachments" not that I didn't believe it. I just doubted it I suppose. And now for the last few days I've been hearing something in my halls. Specifically near the room where my water heater is. Its a voice, like hers calling my name. And I live alone, does anyone have any thoughts or any advice? I ignore it of course. But I'm having restless nights because of it.
