Dream theories were already diverse
Mengyuan Yin begins with traditional ideas about yin, yang, and qi, then argues that dreams cannot be fully explained by that framework alone. It treats dreaming as connected with circumstance, experience, and change rather than as a formula that can be mechanically applied.
Waking experiences may appear in dreams
The text says that what one encounters during the day may appear in dreams at night. In everyday language, recent experiences, impressions, and preoccupations can reappear while we sleep. That is a useful context to notice, not a certain explanation for every dream.
Dreams can change or reverse
The preface lists situations that do not follow their surface appearance: a dream in a satisfied moment may be connected with later loneliness, while a frightening dream may be connected with later celebration. It also mentions dreams thought to correspond only after a long time. These are narrative patterns in a traditional text, not testable prediction rules.
Traditional interpretation contains uncertainty
Mengyuan Yin describes dreams as both potentially meaningful and potentially unreliable. It notes that some were thought to correspond to later events while others never did. That is why this site presents traditional dream material as cultural context for reflection, not as a guarantee about the future.
Historical theory note
