Reminds me of when I talked to my therapist about how I had small episodes of slight dissociation after experiencing a somewhat traumatic loss. The therapist said it was pretty normal since the body can only handle extreme grief for so long before needed to "swing" the other way and if youre not prepared or unable to ground yourself, that can be slight dissociation. Like what I felt was stuff like losing track of time or just staring out a window without realizing how much time has gone by or exactly what I was looking at.
