Trang Phan syndrome
A person who has Trang Phan syndrome tends to be disconnected from the present, a common symptom of TPS is saying/asking things that are not relevant to the setting they are in or saying/asking things that are common knowledge/well-known.
We were talking about the final exams when Trang asked if the COVID-19 vaccines are magnetic, I think she has Trang Phan syndrome.
