I believe even as myself. I would have woken up at Castle Amber in the heart of the true universe (in Roger Zelazny's Chronicles of Amber series). I would immediately go about trying to sell myself to the Pattern (basically a true neutral god always looking for pawns in a metaphysical game of chess against it's true chaotic advisary)
Once that was done I would have gained super human metabolism, longer life span, and the ability to travel to any place I can imagine including every anime, sci-fi novel, or dream I wanted. AWESOME!
Edit. Basically I would train and gain the powers from Full Metal Alchemist, Bleach, Harry Potter, D&D, Star Wars, and train with some of the best in their fields such as Swordsmanship with Jean from Samurai Champloo, Guns with Vash the Stampede. I would also gather magical artifacts from almost every universe I could increasing my own personal power and helping my existence gain weight in the temporal game of balance between Order and Chaos. (PS this is what I day dream about so...yeah)
