Interoception concerns bodily signals; introspection concerns examining one's thoughts and mental experience. A reflection can include both, but interpreting a sensation is different from simply noticing it.

A worked situation: Abdominal sensation

Fictional example. A reader notices an abdominal sensation, then reflects that a deadline worries her. The two entries can coexist without proving the worry caused the sensation.

Keep a signal and a reflection in different cells

An internal sensation is one entry; a thought about what it means is another. Everyday introspection can consider motives, memories, or decisions as well as bodily experience. This terminology comparison helps label the question, but it does not prove perception accuracy, a medical cause, or a condition. Keep "unknown" available in both columns.
