Charak Samhita
ऊर्ध्वदृष्टिर्विपश्यंश्च विभ्रान्ताक्ष इतस्ततः । प्रमुह्यन् वेदनार्तश्च शुष्कास्योऽरतिपीडितः ॥५०॥
The patient looks up with moving eye balls as if he is scared of something. When he gets afflicted with this type of shwasa he suffers from unconsciousness, dryness of mouth, restlessness.
