“The illusions and hallucinations of touch assume still more varied forms [than those of sight, hearing, taste, and smell], and all forms of cutaneous sensibility may occur together or separately. The suggestion of a wound is one of the most curious of these hallucinations; the subject’s description of his suffering varies with the suggestion that the wound was given by a sharp or blunt instrument, but his description is only correct if he has previously experienced one of these accidents. It is still more remarkable that the hallucination of sight is simultaneously developed: the subject sees the blood flow, etc., and a systematic delirium ensues which is more or less persistent, and during which he complains of imaginary suffering, applies appropriate dressings, and carries his arm in a sling, just as if the wound really existed.”
