Can you dream anything you want? How to build a dream scene?

Yes I read about it in Modern Express. It is said that first of all, you should try to recall all your previous dreams (as detailed as possible) after waking up every day for more than a month, and think about your dreams (psychological hints) before going to bed every night.

How to "hatch dreams"

Gail Delaney, a top American dream research psychologist, teaches people how to "hatch dreams": before going to sleep, review the problems to be solved and think about the requirements for dreams. For example, "Please help me understand why I am afraid of flying. What should I do? " Or "What can I do to improve the relationship between husband and wife?" Finally, focus on the bedtime requirements until you fall asleep. Whether you wake up in the middle of the night or in the morning, you immediately write down the contents of the dream and try to understand the information conveyed by the dream. Of course, the more you know how to interpret and read dreams, the more you can understand what dreams tell you.
