Coughing lady

Coughing lady is Clarisse's imaginative friend, whom she encountered during her rich kid vacay.

The Coughing Lady Incident
First encountered when Clarisse was in a hotel in France. She claimed that she heard coughs in the bathroom, despite the fact that no one was there. Believed to be an apparition of a dead person which is believed to appear or become manifest to the living, she is mentioned by her terrified witness as the coughing lady.

Clarisse then broke in a frenzy in the Marina Joyce group chat. Witnesses Rachel, Jia Hui, Ninet and Jana watched her break down while (kind of) trying to console her. Rachel was deprived of her sleep in the process.
