I know a lot of us have trouble remembering our (distant) pasts, such as childhood and adolescence. For me it's a little different. I still have a large percentage of those memories available to me. The problem is that I can no longer tap into the emotional connections associated with those memories and I can no longer experience them in a first person perspective. 

Rather, it's as if I'm just a dispassionate fly on the wall. There's a disconnect, almost a dissociation there, where that person in those memories might as well be a different person entirely, and the other people in those memories might as well be strangers. And a lot of those "strangers" who are still in my life today effectively are strangers, because I don't have those emotional connections anymore due to the disconnect. It's quite an odd feeling, kinda like the universe is expanding away from me.   

On the other hand, shorter term memories like, say, the last two weeks are effectively a blur, with little of note being worth remembering or being remembered at all. I guess a lot of that could be down to a generally repetitive lifestyle. Other by heavy dissociations.   

I don't really have a grand point here, I just wanted to share this perspective of how weird of a feeling it can be where you know something happened but can't remember much of it, or aren't connected to or invested in it.  

Have a goodun.
