I've been experiencing this strange brain sensation, kind of like a vibration, that woke me up suddenly last night. It's happened to me before, a few months ago, and I'm not sure if it's due to stress or maybe not getting enough sleep. As a student, is this something related to my study habits or sleep patterns? It gets worse when I try to go back to sleep or even when I'm reading. After it happens, I can't sleep for about 3 to 4 hours, and the next day my brain feels really jammed. Should I be worried and consider consulting a neurologist about these symptoms?
