Psilohuasca Retreat Netherlands: Back from Peru (March 13th)
This Psilohuasca Retreat in the Netherlands is a unique event for experienced inner travelers. It offers the opportunity to sink deeply into your process of self-awareness, transformation, and inner insight, inspired by the traditions of the Shipibo people of Peru. This retreat includes a unique Psilohuasca ceremony with Eric, held shortly after his dieta with Shipibo shamans in the Peruvian Amazon.
As many of you know, in 2025 Eric spent a full month in the Amazon rainforest undergoing a dieta with Shipibo shamans, a tradition passed down for over 3,000 years. In February 2026, he will return to Peru for advanced study, deepening his knowledge of plant medicines, energetic work, and the healing power of icaros.
Shortly after his return, we will host a special one-time event in which Eric will share his most recent insights, experiences, and newly received icaros with you.
During this ceremony, you will journey with a combination of the ayahuasca vine (Caapi) and psilocybin — a blend known as psilohuasca.
This legal, gentle yet profound combination supports you in going one layer deeper into your process of self-awareness, transformation, and inner clarity.
What to Expect
The event takes place in an intimate, carefully guided setting. From the moment you arrive, you are held in a program fully devoted to rest, awareness, and inner work.
Start: Friday at 1pm
End: Saturday at 13:00
Guided Psilohuasca ceremony with Eric
Integration moments and personal guidance
New icaros brought back from Peru
Time for silence, reflection, and rest
Nourishing meal and overnight stay included
Who Is This For?
For anyone who feels it is time to listen more deeply, gently release old layers, and receive new clarity.
For those who are curious about journeying with Caapi & psilocybin (psilohuasca), interested in the ceremonial approach of the Shipibo, or wishing to build upon previous psychedelic experiences.
A Special Moment to Come Together
Eric brings back not only knowledge from Peru, but also the energy of the tradition he is apprenticing in its simplicity, presence, and the healing power of the icaros.
This event offers a rare opportunity to connect with this lineage directly.
This event is intended for participants who have previously undertaken a deep psychedelic journey with a high dose of psilocybin.

Psilohuasca Retreat Netherlands: Back from Peru (March 13th)
You're signing up for a 2-day retreat in Culemborg starting on Friday 13 March 2026.
Price: € 750
This unique event is facilitated by Eric, who will integrate all his knowledge and experience shortly after returning from his Dieta in Peru into this Psilohuasca ceremony.
The ceremony offers you the opportunity to experience the rituals that the Shipibo incorporate into their ceremonies, helping you to go deeper into your process of self-awareness, transformation, and inner insight.
In the Netherlands, it is legal to purchase and consume psilocybin in the form of ‘magic truffles’. Truffles are a different part of the mushroom, known as sclerotia, which remain dormant and help the mushroom regrow after damage. Magic mushrooms, in contrast, are illegal.
Psilocybin is completely safe when used responsibly in a safe environment with people you know and trust. It is a naturally occurring substance that is converted by the body into psilocin, which acts on the serotonin receptors in the brain. Psilocybin is not addictive and there are no known reports of overdoses.
Psilocybin is not an addictive substance. You may enjoy and get a lot out of the experience, but you’re not likely to become physically dependent on psilocybin.
The age limit of 25 years is installed because the brain is still growing and developing up to that age. Important contra-indications as some disorders are found almost always before the age of 25 (but not always before 20). We must take this contra-indication very seriously because of the immense consequences when things go wrong. And as a young adolescent you rather not come in contact with a very high dose of psilocybin, like participants use in our Retreats.
If you are taking medication, consult your doctor before taking any further steps. Before you sign up for a retreat, please let us know what type of medication you are taking. We can also consult our medical expert to help you gain clarity.

Incredibly profound and mindblowing - Cannabis Retreat
For me, a psychedelic journey is incredibly profound and also mindblowing. Sometimes the journey is abstract, full of feelings an images who are not so clear to me and sometimes is overwhelming, beautiful full of love and a deep feeling in my body and mind. Afterwards the light always conquer the darker images and experiences, even the dark can be seen different. The cannabis journey gave me 2 journey's in one trip, a mindjourney and a different journey in my body. A profound physical experience like a never experienced before.

a unique chance to meet myself, again, to learn how to open kind-heartedly myself to myself
"My retreat was a unique chance to meet myself, again, to learn how to open kind-heartedly myself to myself, to dive deep into a seemingly impossible reflection on my own personality and individuality.
It is personal development not just an experience, it means preparation before the journey, a pleasant yet structured time over a couple of days, learnings and insights to take away and integrate as one returns to everyday life."
Nic

Every journey has taught me a lesson
"I made three journeys, each completely different, but each taught me something. The music and the fantastic guidance of the facilitators helped me calm down and/or experience very deep physical and emotional reactions, both intense and very pleasant. A journey that deeply confronted me with one of my unhelpful patterns that I wanted to break. The next journey brought me 'home to myself' in a very pleasant way. It has given me immense strength, and I expect to be able to shape my life differently through this."

Reconnect with my emotions
"An exciting new endeavor that is nothing like anything I have done before. But which unfolds in a familiar journey through my innerself and where I could reconnect with my emotions in a warm, beautiful and calm setting, Where untrodden paths can suddenly be walked again is a wonderful gift."
Sanne

An unforgettable experience
"It was an unforgettable experience and I look back on our discovery with gratitude. I'm sure there will be more 'loosening up'. I'm looking forward to that. The welcome, care and loving 'holding space' was really overwhelmingly beautiful. You do that incredibly well."
Sandra

It gave me a sense of peace and trust
"Because of my first experience, I was able to step into the second discovery with more trust. That made the journey even deeper and more beautiful, even though some intense themes came up. It gave me a sense of peace and trust — I really enjoyed it."

What an amazing, beautiful experience
"What an amazing, beautiful experience. Words can’t really describe the journey I was allowed to make. The way I experienced it, I would wish this for everyone.

I wouldn’t want to experience my next psychedelic journey anywhere other than at ‘The Matter'
Eric and Marieke have made a dream come true with 'The Matter' — a place for anyone who wants to grow personally with the help of plant medicines.
The yurt, the music, the apartments, the food, the conversations with the coaches, the program, absolutely everything is just right. It creates a calm and safe environment where you can fully surrender and let go in complete trust — and grow from it. I wouldn’t want to experience my next psychedelic journey anywhere other than at ‘The Matter’.

Tears not only of sadness, but also of wonder, insight and clarity
"I'd never experienced this before, though I'd heard a lot about it. The initial intensity was quite intense, but afterward, I felt more peace and surrender. Even though it was a challenging session emotionally, the tears weren't just tears of sadness, but also of wonder, insight, and clarity. I'm glad I experienced it and very grateful for the support Eric, Marieke, and Mirjam provided during the session."

Bauke

An overwhelming gratitude
"I arrived with an intention to connect. There was a sense of celebration, too, because my first real psychedelic experience felt like it would be a reward for all the personal development work I have done over the years. When I left that same evening, what I took with me was an appreciation of opposites; overwhelming gratitude for the loving connection to my wife and son; and a sense of my effortless brilliance, coupled with a deep understanding that, whoever I am, I exist only in relationship – it is solely through connection to the people who cross my path and walk alongside me that I am able to shine."
Jonathan

Dealing with the purest form of all my emotions
"I opened the door to my inner self and spent some time in there, dealing with the purest form of all my emotions, answering my most pressing questions, and making peace with my world and self. Beyond that, I connected with the oneness that we're part of, taking a peek at the building blocks of the journey that we call life."
Cosmin

Connecting to my inner world
"This past weekend it was time for a journey with magic truffles. What a wonderful experience. I was able to quiet my mind (that alone was a relief) and to connect with my inner world and my own authenticity. I felt and saw a lot. For me a journey in a whole new dimension. Eric and Marieke thank you for sharing your fantastic place and for being there as a spaceholder!"

Connecting to my inner self
"In a beautiful place, where I felt safe and comfortable, I got the opportunity to connect to my inner self in a very special journey. Throughout the journey and the aftermath I was be able to give attention to feelings and thoughts that in daily life I easily ignore. This experience created awareness of my soul and peacefulness within myself."
Hester
The Netherlands
It helped me discover things about myself
"It’s like a long psychotherapy done within a weekend. It helped me discover things about myself, let go of what’s unimportant, become more aware and present. The journey I went through helped me live a better life. All I did is trusting the process and the coaching team."
Karolina
Poland
One of the most profound and meaningful experiences in our life
"The psychedelic journeys provided us with direct and easy access to hidden and often un-reachable parts of our mind and soul. It allowed us to connect with ourselves in both profound and spiritual ways. The psychedelic experience allowed us to look at ourselves from new, therapeutic, and healing perspectives, broadening our understanding of ourselves. We find that this experience has a positive and lasting impact on our daily life. This is undoubtedly one of the most profound and meaningful experiences that we have encountered over our life."
