Dreams are residual activities of cerebral cortex, which can better reflect psychological changes and physical health in daily life. However, dreams are not a sign, let alone anything.
If you have encountered difficulties or unhappiness in your life or work recently, you may have nightmares. At this time, it is necessary to maintain a positive and optimistic attitude, communicate with family and friends more, release inner pressure, exercise properly and divert attention.
In short, dreams are not important, what matters is how to treat them. We should treat dreams rationally and don't be overly superstitious about the prediction or analysis of dreams.
