I only use this RC when I'm already sure I'm dreaming and I just want to confirm it - I find a window and punch it out. If I'm dreaming, the entire window pops out in one piece - no broken glass or anything. It's a really weird sensation because I usually hear the glass breaking but the window just pops out of its frame and falls. Then I usually fly out the window. So far I haven't tried this in real life only to find out I'm not dreaming and I just busted my hand.
