For the past few days I have often had a buzzing noise in my head, which usually occurs when there is no noise in my immediate vicinity. 
At the same time as the buzzing, it feels like my head is vibrating from the inside and I'm getting problems with my eyes and my vision gets a bit blurry.

 I've often felt things that weren't there, but the intense vibration and my blurry vision made me worry about it :( 

It's not a migraine or anything like that, I don't have a real headache during it, it's just really really weird
