Expanded animation can be understood through its hybrid character as an artistic practice capable of exploring issues of performativity, social, political, or documentary activism [1], and through a set of mechanisms of dispersed subjectivity activated by the viewer, making it an unfinished work [2] or an artistic experience that can be a source of investigation into contemporary life. Therefore, the present study aims to present: i) the expanded animation project Aneurysm (2022, 10 minutes), which records events from the author's personal life, such as the aneurysm, loneliness, and lack of family communication; ii) and the observational results of users’ interactivity with the installation Aneurysm. Using a practice-based methodology, the concept of animation-space- reception privileges an intimate experience, placing the viewer/participant at the center of the viewing, enabling investigation into how their involvement should be promoted. At the same time, the relationship between reality and abstract animation is discussed, as well as its ability to create 'thinking spaces' for engaging viewers [3]. Aneurysm was presented in 4 main moments, with participation in different festivals, with special mention to Cinanima 2021, from which the observation was carried out through a) a sensory approach, used in the early installation experiences, in which the images and sound appealed to emotions, with a greater impact associated with illness and death for the audience; b) an intimate and narrative approach, with greater individual visual involvement and immersion, focused on the narrative. In this process of iteration, the Aneurysm project evolved progressively, both in its representation (from stop motion animation to 3D animation) and in its mode of interaction (from video projection to interactive installation).

A parte dilatada geralmente apresenta uma parede mais fina, existindo um elevado risco de romper, provocando uma hemorragia. Quando tal acontece, a ameaça de morte pode ser imediata se nada for feito a nível cirúrgico, obrigando a uma hospitalização e intervenção imediatas. Constitui, portanto, uma situação pessoal de
