I don't think it's a stupid question. From my perspective, I have remembered things that I didn't notice consciously at the time such as the location of my wife's car keys. I don't remember their presence grabbing my attention, but later I am able to recall the last place I saw them. Not being a neurologist, I don't see a reason why shutting down the awareness part of the brain would also shut down the sensory processing and commitment of said processing to memory.
