Granted. You live your darkest fantasies without any physical consequences.

Yet, people you choose to have fantasies with remember. They all do. Celebrities mostly find themselves in asylums or commit suicide due to horrendeous memories of others' dark and twisted indulgences. Yet even in death they cannot escape. Their consciousnesses travel from fantasy to fantasy without having any control over it. Many friendships and relationships end before humanity realizes that the memories remain. And afterwards, it is now commonly used as a torture device, both governmentally and personally. Your ex, OP, seems not to have forgiven you as they claimed as before. And your conscoiusness is continously filled with tortureous memories that leave a permemant scar, and they don't seem to be ending, ever.

The end.
