 In the waking state the imaginative faculty is permanently engaged with the rational, appetitive, and sensible faculties. In such a state the sensible faculty is actively working in interaction with sensibles and sense impressions. Likewise, as mentioned, the imaginative faculty provides both the rational and appetitive faculties with these sense impressions. Nevertheless, when in the sleeping state, the sensitive, appetitive, and rational faculties cease their activities, and this is when the imaginative faculty performs a distinctive action of its own. Given that the sensitive faculty is at ease and no longer receiving fresh sense impressions, the imaginative faculty turns now to the impressions preserved in itself, and acts upon them by means of composition and division. Hence, the imaginative faculty has the power to preserve and manipulate sense impressions through composition or division, both in the case of those freshly offered by the senses while in the waking state and those that have been stored in it (al-Fārābī VC: 210–227).
