87. Spontaneous manifestations are not always confined to noises and rappings;
they sometimes degenerate into downright racketing and disturbance, furniture and
other objects are upset, projectiles of all descriptions are hurled from without, windows
are opened and shut by invisible hands, panes of glass are broken; annoyances which
can hardly be set down as illusions.
The confusion thus produced among material objects is often very real ; but
sometimes there is only the appearance of reality. We hear? a rattling in an adjoining
room ; pots and pans appear to be falling about, and breaking with a crash ; logs of
wood seem to be rolling about the floor; we hasten to see what is the matter, but find
everything in order; and we have hardly left the room, before the tumult begins again.
