I've been looking for an exit in my dreams, and I finally found it.

It means to set a goal and be yourself, and the road you choose will succeed in the end. The above is purely superstitious, unreliable and without scientific basis. Dreaming has no substantive meaning and function, as long as you relax and face life positively and optimistically.

When people sleep, nerve cells are widely inhibited, but this inhibition process is incomplete. So some nerves in the cerebral cortex are still excited, which leads to dreams.

It can be seen that dreams occur when a few cells in the cerebral cortex are active. If the activities of a few cells lose the control and regulation of the whole cerebral cortex when they are awake, some fragments of memory will be revived without restraint, then people will have strange dreams.
