Reflected power has to go somewhere. If the sending end is well matched it will indeed be disspated at the sending end. If both ends are badly matched it will bounce back and forth, gradually dissipating in the losses of the transmission line.
It gets more complicated when the terminations have significant reactance. Then as well as reflected real power you'll also have imaginary power. All those VARs still have to go somewhere. They may not be real power, as in making heat, but they are still real amps and volts that can heat up wires and cause flashovers.
