Failed DEILD?

I woke up this morning after a very vivid dream. It was probably around 8 AM or so. I decided to try and DEILD, so I began remembering every detail of the dream. I could actually remember quite a bit of it (I had taken vitamin B6, so that may have helped) in vivid detail. I was in the dream before I knew it, and thus, I didn't attain lucidity. However, I woke up shortly after I continued my dream (probably not even a minute) and couldn't get back to sleep.

What did I do wrong?
