Смысловые Галлюцинации ("Semantic Hallucinations") is a rock band from Russia created in 1989 in Yekaterinburg. The name may be translated as "Hallucinations of meaning", "Semantic hallucinations". Medicine doesn't know this term; it was produced as a slip of the tongue and stuck. The band is also known under a much shorter name "Gliuki" ("Глюки"), a slang term, which means basically the same: glitches in your brain. It was disbanded and recreated again in 1995.
