Duke Zhou: What do you mean by dreaming of an accident?

This may be caused by your recent stress. Let yourself relax properly and choose a suitable trip according to the length of the holiday. Relieve stress.

There is another way you can try:

When you are tired from work or study, find a limb that you think is comfortable. Close your eyes and imagine that you are standing by the sea, flocks of seagulls are flying in the sky, and you are alone on the beach, looking for the best and happiest memories you think. Take a deep breath.

Give it a try, it will help you!
