Hello! I need someone to assist me in understanding some of the calculations involved in quantum mechanics. Specifically, I have questions about the "real wave function" and the "imaginary wave function". I understand that the 'imaginary wave function' is a backward-in-time function and that the 'real wave function' is a forward-in-time function. I also understand that the 'imaginary wave function' refers to a possible experimental outcome in Hilbert space. What does the 'real wave function' refer to? Is there a spatiotemporal point it refers to? Thank you.
