This is why, regardless of the energy therapy definition that we may use, the chakras are pictured like two joined-up funnels or channels (see Figure 1) to suck the universal energy from one end in order to heal and revitalize the body before releasing the unused part of this energy current from the other end.
Nocturnal seizures seem to be caused by changes in electrical activity in the brain that occur during certain stages of sleep. They are associated with certain types of epilepsy and result in sleep disturbance. The lack of sleep affects concentration and performance at school or work.
However, we now understand that a significant cause of nocturnal bruxism is airway instability during sleep, such as what occurs in Upper Airway Resistance Syndrome (UARS) and Obstructive Sleep Apnea (OSA). Intuitively, this makes sense.
