One of the hardest parts of role-playing in a tabletop game is portraying a character with more intelligence, wisdom, or charisma than the player has. You're not the only one to experience this conundrum of trying to imagine something literally beyond your capability, and it doesn't always involve magical monsters!
I remember reading something about how a writer writes a genius character. They can't go forward, as they aren't smart enough - so they start at the end of the situation and work their way back. In hindsight, the clues that the genius saw, are obvious.
