The podcast episodes discussed touch on the topic of synesthesia, a neurological condition where individuals can experience one sense in response to another, such as seeing colors in response to sounds or numbers.

For example, in How the Annunaki Became Ordainers of Destiny with Billy Carson, the host discusses his personal experience with synesthesia, where he sees colors and numbers in response to sounds, which is the reason he often wears sunglasses.

Similarly, in Free Masonry, UFO's, & Bigfoot w/ Jimmy Akin, the guest shares his personal experiences with synesthesia and how it affects his perception, memory, and cognitive processes.

The topic of synesthesia is also briefly mentioned in Bob Odenkirk asks about favorite colors, where the concept of associating colors with numbers or other senses is discussed.
