This is a qualitative, interpretivist interview study undertaken from an inductive, social constructionist perspective.  Eleven pre-registration nurses were asked to use the mental simulation protocol three times per week for 4-weeks.  At the end of the four weeks, semi-structured interviews were employed to co-construct an understanding of their experiences.  This study was carried out using qualitative inductive thematic analysis to search for commonalities in the participants’ experiences.  Several themes and sub-themes emerged from their mental simulation journey, which helped answer the research questions.
