I wish to ***** by snapping my fingers three times, opening a portal to the past where I can either inhabit my past self or appear as my present self. I can also freeze time by clenching my hand for five seconds, allowing only me to move and interact with objects. To return to the present, I will snap three times again, and to unfreeze time, I will snap three times quickly. This ability must work flawlessly, ensuring I am never trapped, can bring objects if needed, and avoid paradoxes or unintended consequences.
