A video reading of the poem, titled "Love Letter From the Afterlife" went viral after Gibson's passing was announced -- with thousands of people saying how much comfort it had brought them.

Gibson’s death was announced on social media by their wife, Megan Falley. Gibson and Falley are the main subjects of the documentary Come See Me in the Good Light, winner of the Festival Favorite Award this year at the Sundance Film Festival and scheduled to air this fall on Apple TV+.

"Though Andrea desperately wished to have lived a longer life, they could not have possibly lived a fuller one," Gibson's family said.
