having a moment

Among other uses of the phrase, "I'm having a moment" can be used when one is experiencing an overwhelming revelation or is reeling from great surprise or shock and therefore cannot respond to further questions or information before processing the emotion/information and/or briefly recontextualising/reevaluating other beliefs.

Speaker A: "Hey did you know that glass doesn't actually flow like a liquid people just installed the uneven glass thick-side-down. Anyway what do you want me to order for lunch?" (Speaker A presents Speaker B in passing with information that contradicts a long-held belief of Speaker B)

Speaker B: "Sorry, I'm just having a moment right now" (Speaker B requests Speaker A to allow them time to process the novel information before commiserating about the next topic of lunch)
