hope believed the secret to a good nights sleep was not in the getting to sleep but rather in the innate ability to know why one was waking up again afterwards ; to instinctively realise it was the start of a new day , or that there was something troubling the person sharing the bed , or that an important detail had been overlooked during the waking hours and was only coming to light in the stillness of rest ; this intangible ability of the subconscious aided sleep much more than a hard lump in the pillow from a gun or knife at least , that was how it had been for hope .
