The claim that dreams cannot predict or manifest future real-world events is a matter of everyday observation and established scientific understanding, requiring no special citation.
The claim asserts the scientific consensus and everyday reality that dreams do not have supernatural or precognitive powers to foretell or manifest future events. While the retrieved papers discuss cultural beliefs in precognitive dreams or psychological factors like paranormal belief and ambiguity tolerance, none establish that dreams actually predict the future. Because this is a commonplace empirical fact grounded in scientific reality, it falls under common knowledge, and citations are unnecessary.
