I have heard of people who create conflicts (non-violent) in their minds (and nowhere else) with other people that don't exist (the conflicts don't exist, not the people involved) and for no particular reason. I remember seeing a word with that definition and I cannot remember it.

A person who experiences unreal conflicts in their mind is "paranoid" or "delusional"
a paranoid personality
paranoid delusions
EDIT - If the person is perfectly aware that the conflict isn't real, a "fantasizer" may fit.
One who fantasizes about nonexistent conflicts deserves the title "masochistic fantasizer"
