You were an older person with mild dementia, so sometimes you often forgot things and confused things.

One day you met a zombie with a tactical gear who you mistook for someone you met in your glory days in the military. Your dementia didn't let you notice that this being was a zombie, you just thought that the war had taken its toll. And for some reason the zombie didn't attack you. He just let you take him by his hand and take him to your home.
