I hit my head about a month and a half ago. I saw an er doctor and was told I had a minor head contusion. Ever since this I keep feeling as though my memories are dreams and when using different computer programs or watching TV or using any form of electronical device (which I m very very familiar with) I feel as though it s foreign/unfamiliar, I can still navigate through them. I don t feel right, as if I m watching from outside.
