Materia Medica Viva – Volume 2 page 509

Kent again gives an excellent description: "when crossing a bridge or high place the thought comes that he might kill himself, or perhaps he might jump off, or what if he should jump off, and sometimes the actual impulse comes to jump off the bridge into the water."
A patient may be sitting on a balcony when the idea comes to his mind, "What would happen if I were to jump off?" Of course, such a thought is not uncommon, but with this patient the thought does not simply pass away. Instead the idea becomes lodged in the patient’s mind, and he begins to fantasize about it. He sees himself getting out of his chair and walking to the edge. He becomes more and more wrapped up in this fantastic scenario as the impulse gains momentum, almost hypnotizing him, until he actually finds himself walking to the railing. Then, just at the moment the impulse reaches its crescendo and he begins to lift his leg over the rail, the image shatters, and the patient returns to his senses. Fearfully, he backs away from the edge and goes inside. In the interview the patient may speak of a fear of heights without volunteering descriptions of such events as the above. This symptomatology seems to be so much a part of his personality that he does not consciously think of it until the impulses reach an alarming proportion. If, however, the homeopathic practitioner describes such a possible scenario to the patient, he will stare in disbelief and exclaim, "My God, yes! How did you know that? You must be some kind of genius!" This statement is typical of the kind of impulsive exclamations frequently made by Argentum nitricum patients.
In another example, the patient may be walking on the sidewalk when he is struck by the idea that perhaps a car will weave off of the road and hit him. He begins to live the accident in his mind and becomes anxious and almost frantic. He sees the car coming toward him, and the fantasy seems to gain momentum. As the fantasy speeds up, so does the patient; he begins to walk faster and faster. As he begins to visualize the car losing control and hears the wheels screeching, he becomes hysterical and verges on breaking into a run. Suddenly he is, in his fantasy, struck by the car, and an image of his crushed and bloody body flashes in his mind. At that instant the fantasy ends with a start, and the patient pauses. "What am I running for?" he wonders and resumes his walk at a normal pace. Thus, the keynote symptom arises – "Anxiety walking, which makes him walk faster."
Often the patient may experience difficulties when crossing a street. He stands at a crosswalk until the light turns green and then begins to cross.
