A meditation practice aims to break the cycle of reliving past emotions, using what is called heart-brain coherence to rehearse a different response.
In this framework, thoughts are the language of the brain and feelings are the language of the body; repeatedly reacting to a memory can condition the body to the past.
Familiar emotions such as anger or fear can become habitual, drawing people back into stressful reactions.
Resting in the present can feel uncomfortable when someone is used to a survival state; staying with that discomfort is part of the meditation practice.
