[85] A very clear and full account of these organic sensations, or
common sensations, has recently appeared from the pen of A. Horwicz in
the _Vierteljahrsschrift fuer wissenschaftliche Philosophie_, iv.
Jahrgang 3tes Heft.

[86] Schopenhauer uses this hypothesis in order to account for the
apparent reality of dream-illusions. He thinks these internal sensations
may be transformed by the "intuitive function" of the brain (by means of
the "forms" of space, time, etc.) into quasi-realities, just as well as
the subjective sensations of light, sound, etc., which arise in the
organs of sense in the absence of external stimuli. (See _Versuch ueber
das Geisterschen: Werke_, vol. v. p. 244, _et seq._)

[88] It is this fact which justifies writers in assigning a prognostic
character to dreams.

[89] A part of the apparent exaggeration in our dream-experiences may be
retrospective, and due to the effect of the impression of wonder which
they leave behind them. (See Struempell, _Die Natur und Entstehung der
Traeume_.)

[91] I was on one occasion able to observe this process going on in the
transition from waking to sleeping. I partly fell asleep when suffering
from toothache. Instantly the successive throbs of pain transformed
themselves into a sequence of visible movements, which I can only
vaguely describe as the forward strides of some menacing adversary.

[92] Even the "unconscious impressions" of waking hours, that is to say,
those impressions which are so fugitive as to leave no psychical trace
behind, may thus rise into the clear light of consciousness during
sleep. Maury relates a curious dream of his own, in which there appeared
a figure that seemed quite strange to him, though he afterwards found
that he must have been in the habit of meeting the original in a street
through which he was accustomed to walk (_loc. cit._, p. 124).

agitation on the interpretation of actual sense-impressions.

[96] It is proved experimentally that the ear has a much closer organic
