I started having migraines not long after starting my day-job, they come every now and then; sometimes even during periods in which I am in no particular type of pressure.
Like a scene from a very poor quality 50s film, all I see is a distortion of everything in front of me and all I hear is static. People I talk to look like nothing but white figures dancing in a dark background. Everthing that surrounds me, no matter how colourful the environment, fades to monochrome.
