This article analyzes the linguistic features of terms related to the Oneirosphere in English and Uzbek, as well as their usage within cultural and national contexts. The Oneirosphere is a set of concepts encompassing the world of human dreams and related notions, and the terms used in this field include not only scientific terminology but also colloquial expressions, mythological concepts, and religious terms. In the course of the study, terms were collected from sources in both languages, and their semantic fields, etymological origins, and stylistic features were examined. It was also found that English terminology is dominated by scientific terms related to psychology and psychoanalysis, whereas Uzbek contains a greater number of terms associated with dream interpretations rooted in folklore, religious sources, and historical traditions. Ushbu tahlil natijalari lingvokulturologiya, tarjimashunoslik hamda madaniyatlararo muloqot sohalarida qo‘llash uchun nazariy va amaliy ahamiyatga ega
