Dormancy

undefined: Dormancy as a whole is a state of inactivity during which a system member, subsystem, or the like will be "asleep" for a certain amount of time, usually marked by difficulty in calling or triggering them to the front.

This could be short-term or long-term, and deep or shallow. Shallow dormancy is when the headmate(s) in question are relatively easy to call or trigger to the front but simply desire to be inactive. Deep dormancy is the more widely known usage for dormancy, where the headmate(s) will be very difficult to call or trigger. They may also not be findable in the headspace.

There are many reasons for (deep) dormancy, usually due to stress/overwhelming emotions put on the member(s) or meant to benefit the system as a whole.
