But, although the above phenomena seem to be equally well known in all countries, there is one peculiar class of apparitions of which I meet with no records but in Germany. I allude to ghosts, who, like those described in the “Seeress of Prevorst,” seek the prayers of the living. In spite of the positive assertions of Kerner, Eschenmayer, and others, that after neglecting no means to investigate the affair, they had been forced into the conviction that the spectres that frequented Frederica Hauffe were not subjective illusions, but real outstanding forms, still, as she was in the somnambulic state, many persons remain persuaded that the whole thing was delusion. It is true, that as those parties were not there, and as all those who did go to the spot came to a different conclusion, this opinion being only the result of preconceived notions or prejudices, and not of calm investigation, is of no value whatever; nevertheless, it is not to be denied that these narrations are very extraordinary; but, perplexing as they are, they by no means stand alone. I find many similar ones noticed in various works, where there has been no somnambule in question. In all cases, these unfortunate spirits appear to have been waiting for some one with whom they could establish a rapport, so as to be able to communicate with them; and this waiting has sometimes endured a century or more. Sometimes they are seen by only one person, at other times by several, with varying degrees of distinctness, appearing to one as a light, to another as a shadowy figure, and to a third as a defined human form. Other testimonies of their presence—as sounds, footsteps, lights, visible removing of solid articles without a visible agent, odors, &c.—are generally perceived by many; in short, the sounds seem audible to all who come to the spot, with the exception of the voice, which in most instances is only heard by the person with whom the rapport is chiefly established. Some cases are related, where a mark like burning is left on the articles seen to be lifted. This is an old persuasion, and has given rise to many a joke. But, upon the hypothesis I have offered, the thing is simple enough: the mark will probably be of the same nature as that left by the electrical fluid;—and it is this particular, and the lights that often accompany spirits, that have caused the notion of material flames, sulphur, brimstone, &c., to be connected with the idea of a future state. According to our views, there can be no difficulty in conceiving that a happy and blessed spirit would emit a mild radiance; while anger or malignity would necessarily alter the character of the effulgence. As whoever wishes to see a number of these cases may have recourse to my translation of the “Seeress of Prevorst,” I will here only relate one, of a very remarkable nature, that occurred in the prison of Weinsberg, in the year 1835.
