Funny things that make you lucid

Double post!
I was in my Ear Training classroom talking with some friends about lucid dreaming. I was telling them that I’ve reached such a conscious state in my dreams that I no longer miss dream signs and I would catch on to anything illogical. Everyone was really interested giving examples of their own dreams and how they’d let the most ridiculous things go by as if it were normal.
“That’s usually the case.” I explained. “But let’s say, I dunno, I saw a blue man just walk by, I’d know something was up. It’s all about being aware of your surroundings.”
“Like that guy?” asked a student pointing to a blue man walking by.
“Yeah, exactly. I’d realize I was dreaming.”

“Wait a second…” I said and burst out laughing as lucidity hit me.
