This happens in the imagination (Arabic mutakhayyila; Greek phantasia), a faculty of the mind already described by Aristotle, which Al Farabi described as serving the rational part of the soul (Arabic 'aql; Greek nous). This faculty of imagination stores sense perceptions (maḥsūsāt), disassembles or recombines them, creates figurative or symbolic images (muḥākāt) of them which then appear in dreams, visualizes present and predicted events in a way different from conscious deliberation (rawiyya). This is under the influence, according to Al Farabi, of the active intellect.
