Personification, also called ordinal-linguistic personification, occurs when a synesthete associates something like a number, letter, or month of the year with a certain personality — for instance, thinking that T is friendly. Objects may also acquire personalities for some synesthetes, according to Synesthesia Test.
Based on their personality, a letter, number, and so forth can also take on a certain appearance, such as that of a person (i.e., because T is friendly it looks like a smiling child) (via PsyBlog). They may have relationships with each other, such as S being T’s mother. They can have feelings, positive or negative, for each other. Again, these associations tend to stay consistent throughout a person’s life, but a new one can develop at any time, according to Synesthesia Tree. This doesn’t apply to situations like a child attributing certain personality traits to a stuffed animal, or even an adult doing the same with a loved object. It also doesn’t coincide with pareidolia, having sympathy towards an inanimate object (via Synesthesia Tree).
