my specialty is weapons 
i can use electronics perfectly, guns, and explsoives, i dont know why, but hey, it works
now, dreaming varies from one person to another, and my dreams are very random, and my specialty in weapons kind of helps in that aspect, becouse i find myself running into very evil thingsa very often.
conjuring things is also my specialty, i think about what weapon or anything else i want at the time, and it pops up where i want it.
i havent tried to transform into anything besides a wolf, and a few other things, but id imagine it works the same.
i find that confidence works the best, but also imagining the thing you want very specificly, and it helps to have an overactive imagination
