又迦延論云。云何一切睡眠相應耶。答曰。或睡不眠相應。如未眠時。身不軟心不軟。身重心重。身瞪瞢心瞪瞢。身憒心憒。身睡心睡。為睡所纏。是謂睡不眠相應。云何眠不睡相應。答曰。不染污心眠夢。是謂眠不睡相應。云何睡眠相應。答曰。染污心眠夢。是謂睡眠相應。云何不睡不眠。答曰。除上爾所事。問眠當言善不善無記耶。答曰。眠或善或不善或無記。云何為善。答曰。善心眠夢。云何不善。答曰。不善心眠夢。云何無記。答曰。除上爾所事。如夢中施與作福。持戒守齋。如善心眠時所作福。當言餘福迴是名善。云何眠時所作不福。當言迴耶。答曰。如夢中殺盜等。如不善心眠餘不福心迴。是名不善。云何眠時所作福不福。不當言迴。答曰。如眠時非福。心非不福心迴。如無記心眠時。所作福非福。不當言迴。是名無記。問夢名何等法。答曰。是五蓋中無明蓋也。

Furthermore, Kātyāyana’s treatise (*Jñānaprasthāna*) states: “How do all sleep and drowsiness correspond? Answer: Sometimes drowsiness is associated while sleep is not: as when one is not yet asleep, the body is not pliant and the mind is not pliant, the body is heavy and the mind is heavy, the body is dazed and the mind is dazed, the body is muddled and the mind is muddled, the body is drowsy and the mind is drowsy, being bound by drowsiness—this is called drowsiness associated while sleep is not. What is sleep associated while drowsiness is not? Answer: dreaming in sleep with an undefiled mind—this is called sleep associated while drowsiness is not. What is sleep and drowsiness associated together? Answer: dreaming in sleep with a defiled mind—this is called sleep and drowsiness associated together. What is neither drowsiness nor sleep? Answer: excluding the matters mentioned above. Question: Should sleep be called wholesome, unwholesome, or indeterminate? Answer: Sleep is either wholesome, unwholesome, or indeterminate. What is wholesome? Answer: dreaming in sleep with a wholesome mind. What is unwholesome? Answer: dreaming in sleep with an unwholesome mind. What is indeterminate? Answer: excluding the matters mentioned above. For example, practicing dāna to create merit, observing precepts, and keeping the fast while in a dream: just as the merit created when sleeping with a wholesome mind, one should say the remaining merit turns around [in dreams]; this is called wholesome. How should the demerit created while sleeping be said to turn around? Answer: as killing, stealing, and so forth in a dream: just as sleeping with an unwholesome mind, the remaining unwholesome mind turns around; this is called unwholesome. How should merit and demerit created while sleeping be said not to turn around? Answer: as when sleeping without merit, the mind does not turn around with demerit; just as when sleeping with an indeterminate mind, the merit or demerit created is not said to turn around; this is called indeterminate. Question: What kind of dharma is a dream called? Answer: It is the hindrance of avidyā among the five hindrances.”
