All day today I kept hearing what sounded like a child's voice. These episodes happened when no one was around. What does this mean?
Auditory hallucination? If it happens again, see your physician. The symptom can have several causes but none of them are good.
maybe its a ghosts.
I'd recommend changing medicines or a more well-rounded diet if you are not on medicines. I personally hated the little girl who haunted me due to excessive cortisone levels in my system a few years back.
Some things that happened some time ago can sometimes come to the surface from your subconscious. As far as ghosts are concerned, I think it all depends on whether you even believe in ghosts.
The soul of your future child is preparing you for parenthood :-)
I think I may have heard that voice too. May I suggest is the alcohol speaking.
