Dream of doing bad things, such as robbing a bank, robbing and killing people.

Let me talk about my understanding of this dream. For reference.

I believe you are an honest man.

You did something illegal in your dream = this "I" is the psychological "ID", that is, an impulse and desire generated in your heart.

[I give priority to primitive impulses and desires and follow the "happiness principle", that is, the satisfaction of desires and the greatest happiness are the greatest goals (even if those desires violate ethics and even laws and regulations). ]

When you see the police, the police will arrest you = this "I" is the psychological "ego" and the police is the psychological "superego"

Ego is the intermediary between ego and superego, responsible for coordinating the relationship between them and following the "realistic principle", that is, to satisfy the impulse of id as much as possible within the scope permitted by superego. ]

People can't have no desire and need to satisfy and vent, but people are social animals and need to follow certain social rules and moral laws. Therefore, he stressed that the stronger the ego, the healthier a person's psychology. On the other hand, if the power of ID or superego is too strong, it is easy to cause some anomalies. ]

Later, your feet were soft or caught = your "id" was restrained, and your inner superego defeated the id, thus making you an honest person. Don't let anything immoral happen to you. So your essence is not bad.
