5-Day Intensive Psychedelic-Assisted Psychotherapy Retreat
With Lucien Heusser and Arinder Sadhra
November 3 - 7, 2026
Where psychedelics can unlock the unconscious, psychoanalysis gives us the tools to decipher it. Together, they do double duty: one opens the hidden material, the other helps us understand the symbols, images, memories, and narratives that organise the way we see ourselves, others, and the world.
Psilara is a 5-day, small-group psychotherapy retreat in the Netherlands for people seeking intensive treatment for trauma, addiction, depression, anxiety, recurring relational patterns, and other persistent psychological difficulties.
What distinguishes the programme is the integration of psilocybin-assisted psychotherapy with psychoanalytic treatment. Psilocybin can bring previously inaccessible emotional and unconscious material into awareness; psychoanalysis provides the clinical framework for understanding what emerges, linking it to longstanding patterns, and working with it therapeutically rather than leaving it as an isolated experience.
Treatment combines psychoanalytic psychotherapy, psychedelic-assisted sessions, trauma-informed and somatic processing, clinical workshops, and extensive preparation and integration. The work is designed to identify and treat the unconscious patterns, conflicts, defences, and past experiences that continue to shape symptoms and behaviour.
The group size is limited to six participants to allow for close clinical attention throughout.
