About me

Hi, I’m Dave Arnold – a Certified Hypnotherapist, Mental Health First Aid Instructor, Suicide First Aid Instructor… and yes, a magician! Rumydion Eclipse is the culmination of everything I’ve learned (and continue to learn) to empower individuals and communities to unlock their potential, break through barriers, and create lives filled with meaning.

Not too long ago, life looked very different for me. I was in a dark place—hopeless and lost. Back then, I was working as an electrician, never imagining the path I’d eventually take. But change was not just possible—it was essential. Step by step, I rebuilt my life. Along the way, I reconnected with something I’d loved as a teenager—magic—and yes, that officially makes me a nerd…but I can live with that! I discovered new passions for hypnotherapy and mental health education stemming from my lived experience so that I could make it my mission to help others. 

The hardest chapter of my life became the spark for an incredible journey. While studying psychotherapy, I stumbled into the world of hypnosis. I was skeptical at first—but the transformations I’ve witnessed since have left me endlessly inspired. I’m not surprised anymore… just deeply moved every time I see someone’s life shift for the better.

Today, I work with the mental health charity Mind, designing and delivering bespoke workshops that educate, inspire, and captivate. My unique approach blends evidence-based mental health training with the art of magic—using illusions as powerful metaphors for resilience, perception, and change.

Whether I’m using hypnotherapy with individuals or groups, training in Mental Health at schools or businesses, or using a magic trick to spark a conversation about hope, my mission is the same: to show people that change isn’t out there, it’s in you, waiting.

About Rumydion Eclipse

Rumydion Eclipse Ltd. is a company I set up that allows me to pursue my journey of helping others…so that they don’t have to go to the dark place I did, and empower people to not only survive but thrive in these modern times.

The name Rumydion Eclipse was an homage to one of the greatest magicians, mentalists, authors and hypnotists of our age Derren Brown. “Eclipse” in its spiritual sense means a powerful moment of transformation. “Rumydion” is taken from an episode of Derren’s where he gave his  wonder drug “R-u-m-y-o-d-i-n” to a number of participants. A drug that had been used in the military to remove fear. And the results were amazing. Yet this was really an experiment in the powerful effects of a placebo (a widely recognised phenomenon in medicine where a fake treatment leads to real improvement in health) and of how the mind can create profound psychological, emotional and physical change within ourselves.

But where the placebo effect differs from hypnosis is that there is no element of deception required. Hypnosis is an ethical and transparent approach to harnessing the power of suggestion for therapeutic purposes – and indeed Derren uses hypnosis in the same series when the effects of the placebo do not work on some individuals.

“Rumydion” is also an anagram of “Your Mind”

“I had all in all about 4 sessions with Dave over the space of a couple of months.
Right from the very first one, I was immediately put at ease. His warm and professional manner, made it such a safe space for me. I felt very able, and comfortable, to speak about my issues with him, and he was, at all times, completely present (so I felt ‘seen’ and understood)
Even before the hypnotherapy part started, there were lots of ‘aha’ moments, as Dave helped me reframe some of the things that had been holding me back (and hence why I had sought this therapy) so I could already see things differently.
I had been concerned that having the sessions over zoom would be weird or less effective…but I couldn’t have been more wrong!
Each session was handled beautifully and I felt so uplifted after each one.
I now understand the stories I have been telling myself (and believing) and have been able to do things differently as a result.
I feel much more confident with what I’m trying to achieve, and have noticed lots of positive changes.
What I like most about the results, are that they are at a pace that feels realistic and manageable…in that, I mean, I have made huge inroads, but they have been acclimated into my system without overwhelm.
I thoroughly recommend Dave, he is incredibly approachable and caring; very understanding…and…importantly, very good at what he does!”
