Everyone has nightmares. In fact, nightmares are the mechanism of human self-protection. When human beings were in the primitive stage, our ancestors should always remind themselves to avoid natural enemies, and they should always be vigilant even when sleeping, and nightmares played a role in waking people up in their sleep and always being alert to external sneak attacks.
If you often have nightmares, are you unhappy or stressed? Or is there something wrong with your body? If it is a physical problem, I suggest you do a comprehensive physical examination; If there is pressure, we must find ways to relieve it. If it is because of emotional reasons, you may wish to talk to trusted relatives and friends to release pressure and emotions.
Treat nightmares with a normal mind, because everyone will have nightmares, people will not have nightmares, and people can't live without nightmares, because, in a sense, it is a wake-up call to our physical and mental health.
Good luck!
