I’ve only had one distinctive WILD so far and it happened by accident. It was so cold in my house that I couldn’t sleep. I woke up and read for an hour. When I went back to bed my eyes began to tremble behind their lids and I could feel vibrations through the length of my body. I directly entered a dream without loss of my rational thought.
This morning I directly entered a dream without trying to WILD, and I didn’t feel any vibrations etc.
Interesting. 
Unfortunately, I still haven’t succeeded at having a lucid dream…
