Memory is something that differs from person to person, I have had carers who can not remember the straight line they have to travel from my house to the shop and I live in a one ended street! others needed reminding every time that I needed to brush my teeth after breakfast. not everyone is good at remembering things, that is why there are so many tricks people can teach themselves to aide memory.
I have dissociation but not did, I can remember my past over vividly, but for as long as I can remember I had difficulty staying focused at school or in meetings...day dreaming is what it was called at school, but often I am not actually having any thoughts at all. I can easily recall in detail things that happened two weeks ago, but for the life of me can't remember what I did two days ago. I have now sussed this out and tell everyone who needs to know that I have a two week turn around for things I have to remember, most people understand this and if I know I need to remember things less than two weeks away I 'write' it on my wrist under a wrist band and transfer it to a diary when I get home!
