first I see that you are new. welcome.

if you look at the bottom of every page you will see this.....

The material on this site is for informational purposes only, and is not a substitute for medical advice,
diagnosis or treatment provided by a qualified health care provider.
Always consult your doctor or mental health professional before trying anything you read here.

what that means is we are able to diagnose or tell you what your own problems are called in you. only your own doctors, therapists, psychiatrists can do that...

(this brings me to your title question of whether this is a dissociative thing in you... my answer sorry I cant answer that. to find out what this is with in you, you will need to contact your own treatment providers off the computer.)

what I can tell you is that in me what you posted was called by many different mental and physical health problems. for example today my hearing voices is from my MS disease (a physical not mental problem), my doctors ended up making some changes to my meds so hopefully I wont be hearing those medication/ ms induced voices. I have also head voices from my dissociative problems, my bipolar problems my sleep problems, my dietary problems... there are so many things that caused/ cause me to hear voices.

my suggestion if this continues to bother you contact your doctors in your off the computer location. they will be able to diagnose and treat you for it.
