I think you're just trying too hard. I'm not exactly sure you were dreaming at that point? Just in SP maybe? I'm not expert but I definitely know what you are talking about.

I sometimes don't get any visuals or sounds when I'm attempting a WILD, just the normal sensations of falling, spinning and flipping (just like you described) and the visuals don't come until after all that stops and I'm actually dreaming. I think you getting stressed about the lack of visuals made you wake up?
