What I mean is, what it the time that you got most mad at yourself when you saw or said something that made it obvious you were dreaming, but never became lucid?

Heres mine:

I was at a friends pool (not sure whos) and everyone from school was there, I went into some group of kids and we started talking about something. I started to realise that this was familiar, and randomly I said "wait a minute, I've had this dream before" then sadly, I continued on and didnt even realise it was dream. I guess I said it was a dream I had before, but never acctually listened to myself.
