This thesis explores to which extent and how a book of exercises made for the subject of modern languages (Spanish) offers support for the pupils' creation of L3+ ideal future selves. By using content analysis and from recommendations of how to create exercises based on Dörnyei and Henrys theories of L2 and L3 future selves, the learning material has been reviewed looking for six themes: "Persons: the self", "persons: others", "places and social contexts" "feelings", authentic matieral" and "possibilities". This study shows a substacial presence (42%) of exercises containing one or more of these themes. The sheer number and variety of these exercises can offer a regular and recurrent support for the pupils experimenting with L3+ ideal future selves. By way of illustrations, contextualization, guiding questions and with the contextual support of the textbook formed as a coherent fictional story many of the exercises are designed to help bring the fantasies and visions to life.
