Abyss, not everyone has only bad memories.
For example here's a short list of my memories, each from a different life and some the same for multiple lives;
General of an alien army(not explaining this one more then I have already), soldier in various Eastern Empires including Rome and China, a supposed "god" for a civilization, a story teller both in Ireland and in the Americas back when the Natives inhabited the land more freely, and I have had many happy and healthy families along my chain of lives.
I've remembered to much to list it all here, but there's a short summary of the best parts. I have also had gruesome deaths, but since it took so much to kill me I'm actually proud of those too. :D
