My shorthand
Remembered = Memory // Intrusive Thoughts
Relived = Flashback
Now… I can zone out & get locked in memories for days. 99:100 I strongly prefer flashbacks, because I’m able to be a helluva lot more functional, as the fully immersive -or worse, fully immersive and moving- tend to be wicked fast. Single sense flashbacks, like screaming pain, or smelling death (my past 16 hours), or hearing air moving that isn’t moving, have legs. But the more the world is erased? Rather than slotting neatly into the world? The faster my brain calls halt. Memories/intrusive thoughts, on the other hand, can knock my legs out from underneath me and allow zero interaction with the world… for very, very long periods of time.
From what you describe? It could have been either intrusive thoughts, or a flashback, or both. Which also happens. When even a millisecond worth of flashback kicks into even days worth can’t-stop-thinking/feeling.
Why I bother to shorthand remembered vs relived? Most kinds of Grounding helps me come back from flashbacks, but just kicks me even harder into intrusive thoughts & memories. So parsing whether I’m remembering or reliving something ends up being a pretty durn vital task for me.
For my own self, my eyes closing means it’s almost always intrusive thoughts/memories. As they’re too immensely overwhelming. Meanwhile my flashbacks happen as I go about my day, because the past and present is actually taking up the same space.
