I guess it worked, then! I have to say, there are a lot of click-baity video titles on youtube, it's rather disappointing. FIVE THINGS YOU SHOULD NEVER DO WHILE LUCID DREAMING!!!

If there was some point to that statement, my best guess is that through a little experimentation we might discover another method which works even better for us. I have also seen posts on forums about people who can no longer get a technique to work, so maybe having more than one method on hand is useful??
