It's very unlikely that you would have complete memories, since the brain doesn't store everything from your present life. Of course they get round this on the other side with technology that stores everything.
I remember two dreams I had which prove this point. If they were indeed dreams! One of them as was on the other side and somebody was there with me, I don't know who, but I must have known them. The were showing me 70's Sheffield, with the passage ways that lead to the Central Bus Station past the car park. It was a replay of the events and they were showing me that I had past by some woman that I currently knew, but at that point had not met. It was very realistic down to the smell from some kind of ventilation system from a building and the smell of urine you get around car parks in city centres were people are cut short from drinking too much! One thing that the real experience didn't have was the thoughts and feelings of the people passing by. But I was more interested in the 70's fashions!
Another dream was a little more mixed up, but shows that everything from your life is recorded and stored for use later or whatever.
Basically in the dream I went to a local dump site, but what was there wasn't anything to do with the site as it is. Instead I found white shelves (in a strange like building) with books, tapes and objects just like you would find in a second hand or charity shop. But it was no charity shop. I remember looking at the objects as if I knew them. I also recall saying I would like to see things from those years, implying something from the future.
It took me a few weeks to work it out what it meant and I can now say what it was. I believe what I was looking at in the Library of my life. All displayed in order of my time on Earth. But it wasn't just a library of objects that I owned, it was the library of object that were thrown out as rubbish or perhaps lost. Hence the dump site reference!
This was clearly a vision (probably personal to me) of the details of my life stored on the other side of life. Each one of us will have something similar and it just goes to prove, despite time and the changing Earth nothing is ever lost. From people to objects.
