There are many possible reasons for dreaming.
1, I haven't slept well recently.
2. What are the stimuli or work pressures?
3, you think about it every day and cause it at night.
Wait a minute.
It is recommended to eat some walnuts, millet, longan rock sugar tea, lotus seeds and so on. Drink some milk to improve sleep.
At the same time, some dreams are signs, so don't believe in superstition too much. You must stop it.
If you really need it, I suggest you see the master.
