This holds good in dream-interpretation too; the interpretation is effected by means of a visual image.

But since the feeling is only very vaguely recognized, this visual image does not answer to the bodily part concerned.

Instead of this, the fancy of the dreamer constructs some visual image which bears a vague resemblance to the proper one, and is generally, if not always, an exaggeration of this in point of extensive magnitude, etc.

For example, a sensation arising from pressure on the bladder, being dimly connected with the presence of a fluid, calls up an image of a flood, and so on.
This mode of dream-interpretation has by some writers been erected into the typical mode, under the name of dream-symbolism.

Thus Scherner, in his interesting though somewhat fanciful work, _Das Leben des Traumes_, contends that the various regions of the body regularly disclose themselves to the dream-fancy under the symbol of a building or group of buildings; a pain in the head calling up, for example, the image of spiders on the ceiling, intestinal sensations exciting an image of a narrow alley, and so on.
