Scherner gives an amusing case of a youth who was permitted to whisper his name into the ear of his obdurate mistress, the consequence of which was that the lady contracted a habit of dreaming about him, which led to a felicitous change of feeling on her part.[82] The two lower senses, smell and taste, seem to play a less-important part in the production of dream-illusions.

Radestock says that the odour of flowers in a room easily leads to visual images of hot-houses, perfumery shops, and so on; and it is probable that the contents of the mouth may occasionally act as a stimulus to the organ of taste, and so give rise to corresponding dreams.

As Radestock observes, these lower sensations do not commonly make known their quality to the sleeper's mind.

They become transformed at once into visual, instead of into olfactory or gustatory percepts.

That is to say, the dreamer does not imagine himself smelling or tasting, but seeing an object.
The contact of objects with the tactual organ is one of the best recognized causes of dreams.
