I'm looking for a word/term that describes someone who creates conflicts that don't exist

Solution 1:

A person who experiences unreal conflicts in their mind is "paranoid" or "delusional"

• paranoid (adj) - having or showing an unreasonable feeling that people are trying to harm you, do not like you, etc. MW

• a paranoid personality

• paranoid delusions

• delusional (adj) - suffering from a false belief or opinion. TFD

• labored under the delusion that success was at hand.
• having delusions of persecution

EDIT - If the person is perfectly aware that the conflict isn't real, a "fantasizer" may fit.

• fantasizer (noun) - one who experiences dreams or daydreams.

One who fantasizes about nonexistent conflicts deserves the title "masochistic fantasizer"

Solution 2:

How about

Eristic: from the ancient Greek word Eris meaning wrangle or strife, often refers to a type of argument where the participants fight and quarrel without any reasonable goal.

The aim usually is to win the argument and/or to engage in a conflict for the sole purpose of wasting time through arguments, not to potentially discover a true or probable answer to any specific question or topic. Eristic is arguing for the sake of conflict as opposed to the seeking of conflict resolution.
