User blog comment:ImperiexSeed/Castiel's shifting of Sam's mental problems made no sense!/@comment-4873164-20120403141655/@comment-4762882-20120404142042

i dont mean wants like money or anything like that...what i mean in regards to taste is that your favorite tastes are all dtermined by your brain...your body's brain can still be alive(only in spn, lol) even if YOU as a person are dead and gone. So things that can affect the brain are still there...Cas sees through Jimmy's eyes, which are connected to the brain, and both the brain and eyes which are connected are being affected by the hallucinations, Therefore, Cas is seing lucifer, even if angels arent affected by hallucinations, the body he is in can see them(alive or dead) which is why Sam didn't just crash after being too tired...it's not something his ears could drown out, it was past the point of anything he could block out.
