Researchers often refer to SP as “Dreaming with one's eyes open.” SP is not a disease. It’s something anyone can get. It can be caused by many things. Some experiences are worse than others. You have to be careful with these more extreme experiences. Someone could feel as if they are going to be injured or even killed while another person could only hear a few voices and footsteps. Most SP experiences are scary and you won’t forget them. Some doctors and researchers say that SP is associated with the Pandafeche attack.
While SP is often a symptom of another sleep disorder. Several factors have been identified that are associated with an increased risk of SP. Which include insomnia and sleep deprivation, stress, overuse of stimulants, physical fatigue and medications used to treat ADHD. Schizophrenia can also be caused by SP. More about Schizophrenia below.
Schizophrenia is a long-term mental disorder of a type involving a breakdown in the relation between thought, emotion, and behavior. Which leads to faulty perception, inappropriate actions and feelings, withdrawal from reality and personal relationships into fantasy and delusion, and a sense of mental fragmentation. REM sleep is rapid eye movement while sleeping. Accordingly, the persistence of impaired activity proper of REM sleep in the prefrontal and parietal cortical circuits necessary for self-reflective awareness and insight, in conflict with wakefulness-related activation of the remaining brain areas, could account for disrupted processing of afferent inputs in our patient, representing the underlying pathophysiologic substrate for the patient’s failure to establish the boundaries between real experience and dream mentation. Pure motor phenomena featured by a dissociated state in which REM- related muscle atonia coexists with a wakefulness state of full consciousness.
