Sighing/breathing woman
It was about 10pm and I had dim lights on in my room to set a relaxed mood as I finished writing, and I heard a woman sigh, like blowing out air, somewhere behind me, and somehow, I knew it was a young woman, with willow limbs and straight auburn hair, just from the sound, like I could see her. I think she's gentle, but tired and cold. But no one was there, obviously, just me alone. I have heard the sound of a child sniffing a few times too when no one was there. But I'm not schizophrenic or anything, so I don't know the cause
