"It was as if I had a good conversation with my subconscious, actually a kind of therapy with myself"
"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."
"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."
"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."
"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."
"It was an intense but unforgettable day and night. I dare say it changed my life forever. In a loving and honest way, Marieke exposed my ingrained habits and beliefs and gave insights that I was not even aware of. The journey, the beautiful location, the delicious food and the beautiful conversations made a deep impression on me."
"Many thanks for the wonderful day and beautiful insights. I wouldn't have missed for the world. I see it as just the beginning of the journey. We see each other again soon."
"If you're reading this, don't hesitate any longer. This is the best place to have psychedelic experiences. The whole team is at your service so that you can have a really good and profound journey. It's wonderful to be here. I can recommend this place without reservation."
"Going to Eric and Marieke is always like coming home. Their hospitality is heartwarming and the location fantastic. The whole concept has a 'worry-free' effect. You can and may let go of everything for a while and focus entirely on yourself and your own process. You will be guided where necessary. The trips are sublimely accompanied by appropriate music and the necessary care. If you would like to take a big leap in personal development and do so in a very beautiful way, this is the place to be!"
A truly special place – beautifully located, lovingly designed, and perfectly equipped. The retreat offers a harmonious balance between natural simplicity and modern comfort, with delicious food and sensitive, well-paced guidance throughout. What stood out most was the thoughtful integration of spiritual depth with a modern approach – without losing the essence and sacred value of the medicine. Everything felt genuine, caring, and deeply aligned. Nothing to improve – simply perfect.
It was again a wonderful experience and so very loving!! Thank you Eric & Marieke
"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."
"We are in the after glow of enjoying an intensely beautiful experience. Thank you so much for your guidance on this beautiful day!"
"Thank you for all the good care. A wonderful experience that I want to cherish for as long as possible."
"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. For me, this is just the first step into a space I definitely want to explore more. Lots of love to these two wonderful people who crossed my path."
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.
What a liberation, I experienced heaven!
You have made sure that you didn't miss anything. You cared for us with so much love and dedication. I felt at home and safe at all times. I couldn't have wished for a better place for my first psychedelic experience. I thank you from the bottom of my heart for these three days full of insights.
"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."
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’.
"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."
A wonderful journey through the unknown. A beautiful start to discover more.
"Thank you so much for our unforgettable experience."
"I was able to embark on my journey with confidence thanks to the team's pure, calm, and grounded support.
The combination of Eric's deep connection, Marieke's loving wisdom, and Noor's embodied care gave me a sense of security.
The environment also offers that peace and safety. The yurt is a stable, comfortable place surrounded by beautiful, lush nature. It's a place where I could sink into relaxed peace, both with and without psychedelics."
"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."
"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."
"What a fantastic experience this was. A true gift to myself. Many thanks for a provoding such a caring and safe environment."
"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."
"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."
"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!"
Eric and Marieke live in a monumental thatched house called “De Tabakschuur” (The Tobacco barn). An exceptional place in the middle of nature, close to the city where you can work on your personal growth in a safe, pleasant and soothing atmosphere.
