Imaginative discussion activities such as "If I woke up tomorrow" make great reflective tools for empathy building and the development of capacity for perspective taking. I can see this particular activity being useful before a COIL/international virtual education experience (or in preparation for study abroad), during a program or course - for example when a critical incident occurs that students need help processing - or after an experience such as in a reentry course or debriefing. For COIL, you should probably tailor the activity so that students are perspective taking relevant to other cultural groups involved in the program. For study abroad, target various subgroups of the host culture.
