I felt like brain was being electrocuted for about 45 seconds. Loud buzzing, flashes of light, headaches, and left ear started bleeding. More to it....?

Head injury. Do you have any recent head injuries? It sounds like you might have had a seizure. Your ear could be bleeding because of injury to the ear canal, ear infection, or something more serious like a tumor or skull fracture. Please see your doctor.
See a physician. Bleeding from the ear is never normal. Need evaluation to rule out more sever cause of your symptoms including mastoiditis, which is a more serious type of ear infection, that can cause more severe difficulties.
