In recent years I have specialized most in depression and negative self-images and how they work on a cellular level. Depression can have a variety of causes, including diet, medication, illness, and emotional setbacks. The mind, or in other words your mindset, can make your body unhealthy and thereby provoke inflammatory depression. It also works the other way around, depression or inflammation in the body cause negative thinking. You can use my knowledge and services to escape from the negative spiral of depression. At the moment I am attending lectures on the combination of behaviour, biology and evolution. This shows that a lot of our behavior goes beyond our own lives. I apply this new knowledge to new sessions.

Details of this retreat
Psilocybin mushroom ceremonies at the Psychedelic Loft in Holland are experiences where participants use a high amount of psilocybin-containing truffles under the guidance of our experienced facilitators. These ceremonies are designed to facilitate a journey into the subconscious, allowing individuals to gain insights, process emotional blockages, and address trauma. The setting is crucial, as the Psychedelic Loft in Schiedam provides a safe and supportive environment for these transformative experiences.
During a truffle ceremony, our participants experience altered states of consciousness, which can lead to personal growth, spiritual development, and enhanced creativity. The ceremonies can be conducted in both individual and group settings, with options for open group ceremonies where participants may connect with others, or private sessions for those seeking more personalized attention.
In addition to the therapeutic aspects, the Psychedelic Loft is designed to enhance the experience with art and a calming atmosphere, which can contribute to the overall journey. After the ceremony, participants often have the option to stay overnight, allowing them to process their experiences in a comfortable setting before returning home.

Prep call
I had a wonderful preparation call with Marcel. He knows all the ins and outs of psilocybin and how it works in the brain. By explaining he took away all the fear that I had to make the next step.
