Through the analysis of a vacillation of the setting during an analysis, and after the end of the lockdown related to the pandemic, the author wonders about the modifications, and even the upheavals of the analytic setting in this unprecedented situation which were to foreshadow a kind of new collective traumatism. In a situation where patient and analyst share a common external reality, which is traumatic in nature and can produce distortions and transformations in analytical listening, it is more necessary than ever to have recourse to ongoing self-analysis in order to enable the analyst to maintain their internal setting, guaranteeing the continuation of the analytical work by supporting the symbolic dimension of their clinical thinking and the analytical status of the process. Finally, the author stresses the need to continue to reflect on the changes in the setting associated with the pandemic, in order to listen to their deferred effects.
