A Montage that brings you inside the mind of a character going mad.
Music is heard - quiet at first, but soon increasing in volume. Characters from several scenes may be superimposed; several Camera Tricks
may come into play here. Some of them may repeat fragments of their lines over and over again, in the manner of a Madness Mantra
. As for the character going mad, they may adopt an Ax-Crazy
expression (if they are about to murder someone) or be screaming at the top of their voice.
