um not sure what you mean... but Im going to take a guess based on reading other posts you have wrote...

from another post of yours it says you are in a mental facility. so based on that Im taking a guess that you feel like those at the facility are taking possession of your body when you are asleep? is that it?

if so in my location that would not fall into the mental disorder DID. here where I am the term possession in the diagnostic criteria is a cultural term that some cultures use to describe who is in control of the body...

example in my native american culture we say "Rainy is in possession of the body", where as non native american's would say "rainy took control of the body". both mean the same thing just worded differently due to cultural language differences.

the diagnostics do not mean possession as in ghosts spirits or others hop into our body's like you see on tv horror shows.

my suggestion is if this continues to bother you talk with one of the staff at the mental facility you are in, they will be able to help keep you safe during the night so that no one can hurt you.
