[2] The album includes guest appearances and production from Monte Booker, Steve Lacy, Kaytranada, Fousheé, Mereba, Smino, Sango, Luke Titus, IAmNobodi, Phoelix and Teo Halm.

Gio Santiago for Pitchfork gave the album a "Best New Music" designation, writing that it "arrives as a mature reintroduction, a love-stained, moody transport that flies through Lenae’s world with a featherlight cadence.

"[17] Rob Murray for Clash opined: "Her first major project since 2018, 'Hypnos' has the feeling of creative release, a sense of emotions expunged and experiences extinguished.

"[18] Jasleen Dhindsa for Loud and Quiet called Hypnos "a colourful and other-worldly debut, aligning with its obvious influences but also way beyond that, capturing the same unconventional essence as Janet Jackson in her '90s prime.

"[19] Andrew Sacher for BrooklynVegan felt that Hypnos "largely follows the atmospheric, lightly psychedelic, downtempo R&B carved out by artists like SZA, Tinashe, and the self-titled Beyoncé album, and Ravyn's got exactly the right soaring voice and lush production style to pull it off.
