The apple-recognition machinery in your brain does not suddenly switch off, and then switch on again later - if it did, we would be more likely to recognize it as a factor, as a requirement.

Actually, the apple-recognition machinery in the human brain really does turn off on a regular basis. You have to be awake in order to recognize an apple; you can't do it while sleeping.

Do you think you wouldn't be able to recognise an apple if you saw it in a dream?
