Why do I have nightmares about my parents' accidents? The scene is even scarier than a horror movie, and I didn't know it was a dream at that time, so I usually do it.

You often have nightmares. Nightmares are like horror movies. You feel nervous, scared and excited. Frequent nightmares show that you are insecure about the environment and depressed, so you will feel nervous, scared and even shout and cry about the horrible scene in your sleep. This is actually a kind of venting. You use dreams to vent your depression. Although such a dream is tense, it is very exciting, and it can also give you a good vent, and you will feel much more comfortable. So you don't reject this dream. My advice to you is to pay more attention to relaxation and venting in life, bravely express what you want, pursue what you really want, get along well with family and friends, and establish a sense of security for the environment, then such nightmares will be less. Good wishes!
