I'm not sure if this counts, but here goes...
I was a kid, still young enough to sleep in my mom's bed. She lay between me and my sister.
So I was having a dream one night, and it was me in the playground. A dude was calling for me, asking who I was. I yelled back, "I AM TESTICLE_BOTFLY!", throwing my hands up...
Meanwhile, in real life, I had announced my name out of nowhere at 5 am. My mother was the most surprised, who discovered what it was like to be woken up by getting punched in the eye.
We still joke about it every now and then.
