This method allows individuals to     \nexplore and modify their subconscious narratives, in \norder to foster changes that resonate through their  \nlives. This differs from traditional hypnotherapy    \nby tapping into eudaemonic aspects of well-being,    \nemphasizing the pursuit of meaning and self          \nrealization.                                         \n\n2 weeks before the first session, they will come to  \nthe lab to record baseline resting EEG (session 0).  \nWith the exception of sessions 1, 4, and 8, all LIGHT\nsessions were performed virtually. For sessions 1,   \n4, and 8, EEG and ECG data was collected.            \nThe first phase of each session was guided relaxation\nor induction followed by prompts to visualize a      \nperfect place of comfort and safely in ones creative \nimagination. Next, they were prompted to visualize   \na path or a set of stairs, and asked to walk down    \nthat path or stairway for ten steps, counting down   \nfrom 10 to 1 outloud. They were guided to visualize  \nand describe a chair or seat, followed by a crown.   \nAfter taking a seat in their imagined chair and      \nputting on the crown, they were encouraged to pause  \nand observe the world they had conjured. Following   \nthis brief period of reflection, awareness was drawn \nto a light or color that emerged from their creative \nmind. They identified the color of the light and     \nwere instructed to imagine that light entering and   \ntraveling through their body, filling up each cell   \nas it passed through. The participant was instructed \nto leave a mental bookmark in this place so that     \nthey could come back to it at any time, before       \nremoving and storing their crown. At the end of the  \nLIGHT sessions, the participant was asked to rise    \nfrom their imagined chair or throne and count their  \nway up from one to ten, with the session ending as   \nthe participant returned to an awake and alert state \nat the end of the ten count.\n\nBaseline recordings were 5 minute of length.         \nHypnotherapy recordings are variable in length with  \nmultiple events indicating a hypnotherapist phase    \ntransitions.
