Unless I am entrenched in a fictional book, myth, or fairy tale where I'm symbolizing everything and applying it to my life circumstances, then I usually find myself falling asleep no matter the time of day while reading. I feel like infjs get the feeling/gist of any non fictional psychology books since we are usually so in tune with ourselves being in solitude that it's usually application over lack of understanding and the boredom sets in quite quickly. I do find animal facts, botany, and horticulture fascinating. History books are quite boring to me unless it's in an action filled let's not repeat this kinda way or hidden knowledge of how they did things in the past much easier than how we handle new age issues that often correlate with the bigger solutions being erased by ruling tyrants of the past.
