last night as I was drifting a sleep I was alarmed and awoken when in my brian it felt like a vibration and than a bang went off! this morning I feel rather cloudy and slightly headachy is this something to worry about? does anyone know what this is?

hey ive actually had the same symptom the other night i was drowsing off in my sleep and i was awoken buy like a vibration kinda thign in my head hard to explain kinda like a shock ... ive had an mri done about a year ago nothing wrong and i was diagnosed with anxiety so it just might be the nervess
