Preface: I'm not denying anyone's experience here; I'm trying to disambiguate a term that has become commonly-used which seems to have some further definitions within its description. This could help us to communicate our experiences more thoroughly, and to reflect on ourselves and hesl our trauma more precisely.
I think different people have different experiences they label as "dissociation."
Today I learned: what I and my psychs have always called "dissociation," is more specifically defined as "derealization" and "depersonalization," depending which of my-self/surroundings is detached or surreal.
"Zoning out" is, as I now understand, is defined as "mild" dissociation, or "ordinary" dissociation; while "traumatic dissociation" is the more extreme form of these things discussed, including the symptoms of "amnesia, absorption, depersonalization, and derealization."
If what I experience and have called "dissociation" happened for even a few days I'd be a dead body, because sitting stationary in place completely shut out into my own headspace staring ahead, not eating or *drinking* or speaking or doing anything physical at all would kill a human being. We need water every 4 days, minimum.
I don't call being up walking around and functioning—but with my attention in another place in my head— "dissociation." My psychiatrists and I have called that "being extremely anxious and overwhelmed by a thought or mood" combined with some other things. Or—"depressed/mental fog."
If I were in that headspace while milling about my day or job duties and then found myself to have stopped what I was doing and had become completely stationary with a blank expression, staring ahead and processing thought, and then were spoken to or disturbed and I reacted to the stimulus, then we would say: "I had just dissociated" for a moment while working. But the mood I was in all day would've been "depressed." Now I know this to be described by the subset terms "dissociative absorption" and "dissociative amnesia," depending whether or not I retain memory of the timespan.
But the fact that there are clearly two headspaces here—one distracted, the other non-functional—suggests and supports that there are separate things going on. The general state of inattentiveness, melancholy, and probably emotional sensitivity/instability is usually described to me by a separate term (like "depression") which may include symptoms of memory loss, inattentiveness, emotional reactivity, etc. as part of its overall description/condition.
The fact someone can still "go on autopilot" and perform even basic functions shows that the brain is multitasking and still responding to stimuli, albeit in a disrupted manner. I now understand highway autopilot is "ordinary dissociation/ordinary dissociative amnesia," while functioning at work and feeling like "nothing is real" to be "derealization."
If one were truly "dissociated" throughout a timeline of experiences—as I've understood it defined and used until now—they would literally not have memory nor learn nor react during that time, so would not be able to perform said functions (like what you've learned to do at work over the course of years in this state of malaise). Kinda what you imagine from media portrayal of a "padded room" patient. Just—there, physically, but not mentally at all.
So I must agree with you folks here; and I just learned something about myself: I've basically been dissociating for my entire life.
We have things to talk about next session. 😪
