I don't think its not so much as the dream signs are fake, as it is just not "clicking' with you that you're in a dream and lucid. Has this been happening a lot frequently? Keep doing what the site suggests and try out techniques to see if you get better results. I can see you are getting very, very close. Keep a dream journal and try to write in it as much as you can after every dream. I had a few dreams like that where I said "Oh, this is a dream." But it never clicked with me per say that I was dreaming.

Have you ever been lucid before? Also don't let this discourage you. ^_^
