Critical reception
Entertainment Weekly wrote that "the sheer heaviness of the old Swervies is much missed, but even on cruise control the band has a singular intensity, not to mention a sharp sense of songcraft." MTV called the album "packed with odes to psychedelia and mesmerizing sonic displays that draw heavily from [Swervedriver's] post-punk past." The Quietus praised the "warm, spacey psychedelia and classic pop hooks." CMJ New Music Monthly wrote that "the band's ability to strike a balance between restraint and reckless abandon is way more impressive than even the catchiest of melodies." Stuart Berman of Pitchfork stated that even if the band "may not have envisioned 99th Dream as a swan song, the album's wistfully nostalgic lyrics and comedown vibe made it the most existential in their catalog".
