no I didn't have alters that were always asleep. my alters were dissociative related as in when I dissociated (felt numb, spaced out, disconnected) my alters would take control to handle what ever situation was causing me to have my dissociative symptoms, and the resulting alter that took control were the alters that dealt with that specific situation.....

example....

if I was having a problem with intimacy and started emotionally feeling numb, spaced out and disconnected during an intimate moment, my alter Thelma was the one that took control because Thelma was my sexualized / intimacy alter.

one of my triggers that used to cause me to have my dissociative symptoms was rain and storms. when I had my dissociative symptoms due to rain and storms my alter Rainy would take control and handle that situation.

my internal system worked like this where any time I was triggered into having my dissociative symptoms the resulting alter that handled that took control and did what was needed at that moment.

even at night time my system didn't have the element of "sleep" built into it. if I was having a problem at night, and had my dissociative symptoms, which ever alter handled that trigger took control and took care of things.

my therapist and I once had me go through an inpatient observation/ sleep study because she could not believe I could literally go weeks on end with absolutely no sleep, just because I was in a phase where I was having nightmares. the sleep study showed the moment I started getting ready for bed and had my dissociative symptoms an alter took control and that alter did their thing of wandering around to make sure everything was safe and sound then settled down with a book and read all night long, then when it was time for breakfast the alter that dealt with getting up, dressed and breakfast took control to handle the morning routine. then when it was time to go to work the alter that handled the job skills needed for my work took control,.. this went on and on day after day after day where because I was dissociated so the alters did their jobs, purpose and reasons why they were created and handled things.

my system was more natural, as in dissociative related instead of mental rooms, and alters sleeping or playing in mental playrooms.

one of my therapists one time even tried to help me build a mental play/ sleep area in my mind to help me get more sleep. all that happened was normal relaxation visualization where I could use my imagination to imagine and daydream about having such a place in my mind but it never ended up being an actual dissociative space in my mind like others have. I think that the reason why I didn't have a sleep/ play room as part of my system is because during the actual trauma's that I went through I didn't need a mental sleep play room, I needed the alters that handled the trauma's and literally get me out of the mine shafts where the abuse happened and safely home. because my mind didn't create that kind of system I cant create it now. I can use relaxation and visualization through my imagination skills which is different then having sleep and play areas in my brain for alters to sleep all the time.

my suggestion since you do have an alter that just stays inside, never takes control just sleeps. look back on your life and see where that has happened before in your life. DID is a problem that begins in very early childhood so this has been happening for you all your life. you can use your history of this happening to figure it out. check out things like what causes you to dissociate, what your triggers are and when are the times when this alter has just slept. maybe ask inside how and why your system needed to create an alter that just slept.
