Many mental illnesses appear with some precursors. However, many people do not take them seriously, thinking that time will wash away these uncomfortable symptoms, and when they find that they have affected their lives, they are no longer able to self-regulate. Here are some precursors of emotional paralysis. If they appear in your case, please make sure to seek professional help in time. Normal people can hear knocking and calling sounds when they are stressed, and upon confirmation can realize that they are hallucinatory phenomena, medically known as psychogenic hallucinations. Occasional hallucinations in normal people before going to bed and before waking up cannot be considered as pathological. However, if such hallucinations occur frequently, such as seeing some abnormal phenomena, then it is important to pay attention because hallucinations are a symptom of schizophrenia. We may talk to ourselves when we are under too much psychological stress, but if we talk to ourselves or laugh to ourselves too often, then be aware that this is also a symptom of schizophrenia. Delusions are not daydreams. Delusions are a symptom of mental illness. For example, if you suspect that people are talking about you when we walk into the office and they stop talking, then pay attention. Many people see minor discomfort as a serious illness and repeatedly check it several times, but it is normal to be able to follow the doctor’s advice after examinations such as ruling out related diseases. If you are skeptical of the doctor’s words and cannot remove your suspicions, then hypochondria is not excluded.
