Correct me if I’m wrong, but I believe that the topic or revisiting past memories has been mentioned in one of the quests. I’ll need to check into that—here it is!
Although I haven’t tried it myself, I had always assumed that attempting to do this would result in the subconscious creating situations and memories that may have never really happened, but somehow could have. As a result, I wouldn’t be too sure that these memories would be of actual real life situations.
Then again, I suppose that there are plenty of memories hidden away in the subconscious mind that we don’t know of, but it’s still an interesting idea either way.
