I just had my first LD last night in which I tried to learn how to throw fireballs. In the dream I asked my brother how to make fireballs, and he taught me how to make these little colored dots appear in my fingers and shoot patterns onto walls. Unfortunately they werent actual fireballs like I wanted. I kept asking to teach me how to make fireballs but he never would tell me. How do I find out how to do stuff like this?
