4. Thoughts drop into your mind from nowhere.
If you're clairvoyant, you'll likely see visions or colors or pictures others can't see. If you're clairaudient, you'll hear sounds or voices or even music that other people can't hear. If you're clairsentient, you'll feel things in your body. But if you're claircognizant, you'll just know things you shouldn't know, which can make this the hardest form of intuition to recognize, because you'll think it's just a thought. But these thoughts don't feel like you thought them up. They're more like flavors you come to recognize over time.
