dream sleep
Introduction
Introduction In some states, including dreaming, fantasy and self are separated, and people will not perceive that they are fantasizing. "Fantasy" is an illusion that the information is taken out of the sensory memory and then sent back to the sensory area. The purpose of the dream illusion is to replace the real signal with a simulated sensory signal, driving the autonomic nervous system to perform the psychosomatic role.
Cause
Cause
Can occur in high fever, epilepsy and other diseases. It can also occur in some abnormal psychological states. Under this state of mind, patients give up objects based on objective and real ideas, reacting with their own psychological state, and regard them as characteristics of external stimuli.
When the deep temporal lobes are tumors, there may be episodes of abnormal behavior, often accompanied by dreams. The patient has a dreamy feeling, like a strange feeling in a dream, often accompanied by illusion, like returning to childhood, or panic.

The patient has a dreamy feeling, like a strange feeling in a dream, often accompanied by a illusion. A feeling, due to the lack of corresponding realistic stimuli, the objective test results prove that this feeling is illusory, but in terms of the patient's own experience, it does not feel illusory. Some patients believe that their feelings come from objective reality.
Diagnosis
Differential diagnosis
True illusion, the spontaneous excitement of the cerebral cortex receptive area makes the previous image active and reappears, which is the appearance. Because the appearance is particularly strong, vivid, vivid and detailed, "projecting" to the external objective world. "Projection" means that when the intensity of the representation is so large that it is as much as the image generated by the actual stimulus, it cannot be distinguished from the realistic stimulus image in human consciousness, but it is customary to think that it is from objective. Space, so this is a natural outward projection process.
False illusion, if the reproduction of the image traces is only to the extent equivalent to the appearance, not so vivid, vivid, detailed, only active in the mind, not "projecting" to the objective world, and it is small random, then It is a false illusion.
Residual illusion, an illusion that lasts for a long time and is not closely related to mood, is often seen in patients with schizophrenia.
From the physiology of illusion, it can be divided into the following categories:
Auditory hallucination: refers to the sounds from the outside world that the patient hears without real external sound stimulation. These sounds can be voices, music sounds, etc., but also some discussion sounds. Patients may sometimes obey orders from these auditory sounds and cause danger. Phantom: In the absence of true visual stimuli, the patient can see images that do not exist.
Illusion: The feeling that the patient feels touched without real tactile stimulation. It can be felt from a human touch, or it can be felt from a touch from an animal. The incidence of temporal lobe tumors ranks second in cerebral hemisphere tumors, second only to the incidence of frontal lobe tumors. Common tumors are gliomas, accounting for 17.96% of the total number of intracranial gliomas, followed by meningioma, which accounts for 5.42% of the total number of intracranial meningiomas. In addition, metastases often occur in this area. Adults are more common and gender differences are not obvious. The function of temporal lobe is very complicated, and the function of some parts is not completely clear. In the early stage of the temporal lobe tumor, there are many typical clinical symptoms, and the diagnosis is difficult. Especially the tumor is located on the right side, and most of them only show symptoms of increased intracranial pressure. It has few symptoms and signs, so it has been called "quiet zone" or "dumb zone" in clinical practice, so early diagnosis is more difficult.
