Sometimes I suffer from indigestion of the mind.

The metaphor of “indigestion” shifts a bodily complaint into the realm of thought: the speaker has taken in more ideas, worries, or impressions than can be comfortably processed. It suggests mental overload—rumination, anxiety, or an excess of information—that sits heavily and resists assimilation, much as rich food can. The phrasing also implies that thinking is not purely abstract but embodied, with emotional and physiological consequences. In a single line, the quote captures a familiar modern condition: the mind can become congested by what it consumes, and relief may require rest, simplification, or time to “digest” experience.
