Gazing into a ball of crystal or glass, a crystal or other smooth ring stone, such as a sapphire or ruby, or even into a common ink-pot, they will see visions very brilliant.

These are often mere reminiscences of faces or places, occasionally of faces or places sunk deep below the ordinary memory.

Still more frequently they represent fantastic landscapes and romantic scenes, as in an historical novel, with people in odd costumes coming, going and acting.

Thus I have been present when a lady saw in a glass ball a man in white Oriental costume kneeling beside a leaping fountain of fire.

Presently a hand appeared pointing downwards through the flame.
The _first_ vision seen pretty often represents an invalid in bed.
Printed words are occasionally read in the glass, as also happens in the visions beheld with shut eyes before sleeping.
All these kinds of things, in fact, are common in our visions between sleeping and waking (illusions hypnagogiques).
