[5] On April 9, 2019, Pvris frontwoman Lynn Gunn posted a video on her Instagram featuring a few seconds of some previously unheard music, captioning the photo "She's been quiet but she's been WORKIN' (and practicing her winking)".

"[7] While Pvris' previous albums had been produced with Blake Harnage, Hallucinations was produced in collaboration with a variety of other artists, most notably JT Daly, who assisted in rewriting several songs for the EP with Gunn.

[8] Marshmello and Amy Allen cowrote the second, eponymous single from Hallucinations with Gunn.

[9] Gunn stated in an interview with Rock Sound that writing begun for the EP at some point during 2016.

I was in a hotel room and made the demo at my hotel and it's kinda been an ongoing work in progress for the last 3 years and then finally once we started working with JT Daly, who did "Death of Me" and "Hallucinations," we started going through a lot of old demos and reworking them and that was one we picked out and it came out really cool.

[4] This was later confirmed October 19, 2019 on the band's Instagram when they posted the album's title and cover art.

Frontwoman Lynn Gunn later stated on Twitter that those vinyl were a limited edition of only 500 copies.

[15][16] "Hallucinations", "Death of Me" and "Old Wounds” are on the band's third album Use Me, released on August 28, 2020.
