Hello, tell you in detail, in fact, dreams are just a psychological activity when people sleep. Psychological activities in dreams are the same as those when people are awake, and they are the reflection of objective things in the human brain. Most of them have no special meaning. Most of the bizarre things in dreams are caused by the illusion of stimulating various objective things when people are unconscious during sleep. For example, the palpitation (palpitation) caused by a person's tachycardia (that is, his heart beats slightly faster) during the day will turn into a bizarre and terrible nightmare that is chased by people. So, don't worry too much about dreams.
