Hilary Mantel

If you get stuck, get away from your desk. Take a walk, take a bath, go to sleep, make a pie, draw, listen to music, meditate, exercise; whatever you do, don't just stick there scowling at the problem. But don't make telephone calls or go to a party; if you do, other people's words will pour in where your lost words should be.

I think hallucinations need to be discussed. There are all sorts of hallucinations, and then many sorts which are okay, like the ones I think which most of us have in bed at night before we fall asleep, when we can see all sorts of patterns or faces and scenes.
