Please comment on my writing of an introduction to my research paper and point out any grammatical errors. THANK YOU in advance

Dreams
Over the century, peoples have always interested in dreams. Dreams are the mental activity that takes place during our sleep. Normally, people dreams two or three times when they are asleep. The inability to recall dreams is not abnormal though. Dreams are communication of the body, mind, and spirit in a symbolic state. The human brains are in constant activity when sleeping. For thousands of years, dreams were regarded as a message from Gods. Dreams seem to be a way for the subconscious mind to sort out and process all the input that is encountered while people are awake. “Dreams may contain ineluctable truths, philosophical pronouncements, illusions, wild fantasies, memories, plans, anticipations, irrational experiences, even telepathic visions ... The dream is specifically the utterance of the unconscious ... our dream psyche possesses a wealth of contents and living forms equal to or even greater than those of the conscious mind (Jung, 1974, pp. 95-96). Dreams play a significant role in our lives: it has a meaning, it helps us diagnose our inner mental illness, and it shows us a path for the future.

I think I would use "inner conflicts", rather than mental illness.
