Not really. In fact, my DP/DR causes me to want to look back to make sure I remember things, which I do. However, I will say that being in this state, I often question if memories are real or actually happened. Then the existential questioning comes up "what creates memories? Why do we have memories? Etc"
What I will say is back when I dealt with this when I was 17....well, basically my memories of those 5 months of DP/DR are strong. If you were to ask me what I did on Christmas 2013 when I had no DP/DR at all, I couldn't tell you. If you asked me what I did on March 17th on a Tuesday at so-and-so time when I was 17 and dealing with DP/DR, I can recall most everything. I think when we're in this state, we're a lot more aware and conscious than we give ourselves credit for.
As for you, it could be that you're focused so much on memories that they begin to look a bit jargled. I believe a lot of us with DP/DR are simply too focused on what's in our head at any given moment and it amplifies our fears and thoughts.
