What Could Be Causing Blurred Vision, Cognitive Issues, Visual Disturbances, Ear Pain, And Unusual Dream Experiences?

I ve recently started experiencing a variety of different issues including: -blurred vision (can t focus) -harder time keeping a consistent narrative moment to moment -moving textures in my visual field (when looking at the wall, some of the textures are waving) -general cognition/memory issues -my thought stream is very quiet, in general I feel empty I also started feeling some pain in my ear. In one recent dream I heard an extremely loud thunder cracking noise, and I never noticed hearing stuff in my dreams until now I eat healthy, exercise often, and get good sleep so I m not sure what s going on, any ideas?
