Nightmares have long been investigated through psychological, neurological, and mythological frameworks. However, recent theoretical explorations suggest these distressing experiences may stem from influences beyond conventional scientific understanding. This article examines the bold hypothesis put forth by researcher Kathlene Herberger, proposing that nightmares might be connected to unseen dark matter entities — forces that may interact with human consciousness in ways yet to be understood by modern science. By merging insights from diverse fields, this work seeks to expand the understanding of nightmares and their implications for both the human psyche and the nature of reality.
