First of all, to comfort you, having nightmares doesn't necessarily mean bad luck. You don't have to worry so much. This is an authoritative scientific proof that everyone dreams after falling asleep, at least four times. This is due to the slow movement of human organs and the coordination of the brain. After dreaming, people may remember the content of the dream, but more often they don't, because the brain often opens the protective barrier and omits the content that is too exciting in the dream, so most people can only remember 10% of the dream, and the remaining 90% is too exciting and ignored by the brain. So nightmares are common, you don't have to be too afraid.
In addition, from the point of view of the Duke of Zhou, there may be some small problems in your heart that have been bothering you, making you subconsciously worry about your daughter, but you hope that such worry is unnecessary, so your daughter says to you, "But it will come back."
Just relax。 It's okay to have nightmares. If a person has no memory of dreaming, it can only show that his dream is extremely horrible.
