Yea I think that might have been part of the SP. When I had my first WILD, I felt something similar. I tried not to focus on it, and somehow, a few seconds later, the dream started forming right before my eyes! It was incredible. It was also very hard for me to transition into the dream, it took a while to get myself "in" it.

Next time it happens, try to just visualize what you wanna see maybe? If it doesn't work, try another approach. Sooner or later you'll find something that works well for you Good luck!
