On “Ghost,” Justin Bieber sings about losing a loved one, whether from death or them walking out of his life. The song also accounts for how people could not see their families during the COVID-19 pandemic, in which areas enforced social distancing guidelines.

In a Tweet from February 20, 2022, Jon Bellion backgrounds the inspiration of the song:

Wrote this one about my grandmother. Really cool to feel her every time I turn the radio on in the car. Miss you Gma.

On February 26, 2021, Justin’s paternal grandfather, George, passed away unexpectedly in his house, the same day that Justin announced Justice. The cause of his death is unknown, but it could be a major factor in what Justin croons about in the song.
