Hypnotizing Maria von Richard Bach

Flight instructor Jamie Forbes guides a woman to landing her plane safely after her husband loses consciousness, then flies on to his own destination unimpressed by his act . . . flight instructors guide students every day.

Only after she tells reporters that a stranger appeared in an airplane alongside hers and hypnotized her into landing, and after he meets his own guiding stranger does he solve the bigger mystery: how each of us creates, step by step, what seems to be the solid world around us.
