This spell is a part of the Flashback spell chain and is found in the Flashback rune stone.
Rumination has been building toward this. The Flashback chain began with a sudden involuntary memory, escalated through physical pain and never ending suffering, reached into the target's worst experiences with Tortured Past, and stripped away their most recent learning with Rumination's Confusion. Each spell in the chain has taken something from the target - a moment of focus, a measure of health, a piece of capability. Rumination's Dislocation takes something more fundamental than any of those. It takes their ability to locate themselves in the world.
When this spell is cast Rumination reaches into the target's spatial memory - the part of their mind that knows where things are, that maps the environment and tracks the positions of those within it - and twists it until nothing corresponds to anything. Everyone in the target's perception appears to be somewhere they are not. The ally standing to the left is perceived as standing somewhere impossible. The enemy directly ahead seems to be elsewhere entirely. Every time the target moves, a pit seems to open before them - not a real pit, but a memory of falling, of edges, of the particular terror of ground that isn't there, dredged up by Rumination and placed directly in the path of every step.
If anyone, friend or foe, is actually adjacent to the target, Rumination's distortion ensures the target perceives them as a threat, and attacks accordingly, unable to distinguish ally from enemy in a world where nothing is where it appears to be. Each round the target may make an Impossible Insight check to pierce the dislocation briefly and see reality as it actually is. Failure means another round of Rumination's geography, where every direction is wrong and every step is toward a danger that only exists in the past.
