  Generative AI tools introduce new and accessible forms of media creation for
youth. They also raise ethical concerns about the generation of fake media,
data protection, privacy and ownership of AI-generated art. Since generative AI
is already being used in products used by youth, it is critical that they
understand how these tools work and how they can be used or misused. In this
work, we facilitated students' generative AI learning through expression of
their imagined future identities. We designed a learning workshop - Dreaming
with AI - where students learned about the inner workings of generative AI
tools, used text-to-image generation algorithms to create their imaged future
dreams, reflected on the potential benefits and harms of generative AI tools
and voiced their opinions about policies for the use of these tools in
classrooms. In this paper, we present the learning activities and experiences
of 34 high school students who engaged in our workshops. Students reached
creative learning objectives by using prompt engineering to create their future
dreams, gained technical knowledge by learning the abilities, limitations,
text-visual mappings and applications of generative AI, and identified most
potential societal benefits and harms of generative AI.
