If your power is future sight, then there is a way your visions will be given to you, instead of you writing them yourself. Whether you're actively trying to receive a premonition, or not expecting it at all, it will be made clear you get one because The Powers That Be will create a separate post, detailing exactly what happens in your premonition. This could happen anywhere, and at any time, and even concern any thing! So expect the unexpected, and don't forget that as you grow as a character, your powers will grow too!
