Swapna Shashtra is not a standard canonical Jain text. In Jain literature, dreams are discussed in traditional sources and in later compendia, not under a single work titled “Swapna Shashtra.”

Key related names you might be looking for:

• Swapna Samhita (स्वप्नसंहिता) — a Hindi dream-interpretation manual compiled in the modern period; focuses on what dreams signify and how to interpret them.
• Swapna Jyotish (स्वप्नज्योतिष) — another Hindi volume on dream interpretation, also produced in the late 20th century.
• Traditional Jain references to dreams also appear in classical sources like the Bhagavati Sutra, which discusses auspicious and inauspicious dreams connected with the births and futures of great souls (e.g., Mahavira and other Tirthankaras). In Digambara and Śvetāmbara traditions the number and details of these dreams are described somewhat differently (often 14 or 16), but these are part of devotional and narrative material rather than a single “Swapna Shashtra.”

If you’re seeking something specific in JainKnowledge, I can help look for a page about these dream texts or the 14/16 auspicious dreams and point you to the exact JainKnowledge entry.
