With the spread of COVID-19 and the replacement of face-to-face classes with emergency online learning, many studies have investigated English as a Foreign Language learners’ perceptions regarding their experiences of emergency online learning. However, the influence of EFL learners’ proficiency levels on their perceptions is still a neglected area. Conducting in-depth interviews with a group of Libyan EFL learners (n=18) by employing the Zaltman Metaphor Elicitation Technique, this study investigated their metaphorical perceptions regarding emergency online learning across the three proficiency levels of Basic, Independent, and Proficient Users according to the Common European Framework of Reference for Languages. Considering the large number of EFL learners around the world and the felt literature gap, this study investigated the relationship between EFL learners’ proficiency levels and perceptions. The three main features of online learning reflected in the participants’ metaphors were (i) lack of the teacher’s physical presence, (ii) lack of peers’ physical presence and (iii) lack of nonverbal communication cues. Furthermore, this study reveals a significant relationship between the learners’ language proficiency levels and perceptions. For instance, Basic Users perceived the lack of a teacher’s presence by metaphors of ‘unsafety’ and ‘fear’, while Independent and Proficient Users respectively perceived it by metaphors of ‘freedom’ and ‘power’. Accordingly, the learners reported different class behaviors and learning strategies in response to these features
