How does EMDR work and what happens in a session?
EMDR combines brief attention to a distressing memory with attention to an alternating stimulus. It is delivered within a phased protocol; eye movements are one part of the process, not the whole therapy.
In an EMDR session, therapist and client identify a target and notice related images, beliefs, emotions and physical sensations during short sets of bilateral stimulation. The work is monitored and closed in a structured way.
Before processing
Early phases cover history, goals, risk assessment and resources for managing emotional activation. If preparation is skipped, it is reasonable to ask why.
During bilateral sets
The therapist may ask you to follow their fingers, listen to alternating tones or use tapping. After each set they ask what you notice. There is no correct answer and no need to force a conclusion.
Closure and reevaluation
A session should leave enough time to return attention to the present and review how you feel. At the next appointment the target and any changes are reassessed. Dreams, emotions or new associations may arise between sessions, so agree in advance how to seek support.
What we know about the mechanism
Proposed explanations involve working memory, orienting responses and adaptive information processing. Research has not established a single definitive mechanism. A careful explanation does not present a theory as settled biology.
