"saw you dancing on a tightrope" is about the effects of displacement and how the passage of time affects memories. And as a result, what it is like to grieve someone who you have very few memories of. The photograph in the video was printed on glass, as away to represent memories. That only key moments/ factors are remembered while the rest fades away.
The dress Christiana wears in the video is from her grandmother who died in 2021. In Sierra Leonean culture, instead of throwing away clothes owned by someone who has died, it is passed down to family members. The photograph is of Christiana's mom and sister on the beach where her grandmother was buried. By adding these two elements Christiana attempts to also speak to how we keep those who have passed on alive.
