I'll skip the details of this long dream and get to the good part.
My sister was asleep on a chair, and at first I just tried to wake her up. I then said something like
"Kristy! You're dreaming! You gotta do a lucid dream remember?"
Then I started trying to hypnotise her into getting a lucid dream while she was still asleep.

I guess my subconscious was trying to tell me something...?
