I usually get voices or music too (even when not in a severe episode), but every now and then during severe episodes I get visual too, like an alternate shadow version of my cat that darted around my vision when I was alone for two weeks and almost lost it. This was during a really deep depression. I've also seen bugs like giant spiders, rats, shadow people. And during my highest mania I saw beautiful rainbowy lights emanating from lightbulbs and surrounding people and flowing around like auras.

Are you still seeing these things? Are you in an episode right now?
