One question. Are you trying this as you go to bed? It's a lot harder to do when you are ready for sleep.
It's best to sleep for five or six hours, and then try it.
Here's my tips.

Go to sleep for five or six hours. Wake up and write down whatever dreams you remember. Stay awake for a time.
After about an hour or so, you go back to bed and go to sleep. (try to make sure you do this at a time when you aren't going to be disturbed.)
While awake, try doing something that's dreaming related, browsing this forum, reading your dj.
I tend to think about what i'd like to dream about next, set the scene in my imagination and work out which dreamsign i'm going to use.
Go back to bed, telling yourself that you will spot your dreamsign, and recognise that you are dreaming.
If you don't have a WILD, you'll at least have another dream to recall.
Hope that helps!
