A trance journey is right for you if you, for ex....
...are looking for fulfillment, your life mission or if you long for deeper more loving connection and relationships in your life
...have tried a lot of things in the past but haven't made any progress with the usual "self-help tools" (e.g., Mind-set work, addressing your belief systems and blockages with coaching questions, positive thinking, affirmations or inner child work)
...want to explore and go beyond the limitations of your potential and consciousness, and want real change
...wish for a better or deeper connection with your Soul and intuition
...feel an inner "calling" to open the door to the great mystery within
...go through a spiritual awakening or suspect that you do
etc.
Of course, not everything needs to apply, these are only some examples. In any case, it's advisable to bring curiosity, openness and personal responsibility to this kind of work. Also, this work requires psychological stability (please also read: "When is a trance journey not right for me?")
