I have done the same thing, however I felt different effects.
However, I don't think that its possible to lucid dream by doing it "right" before bed. Try combining a WBTB with a WILD.
I haven't had a lucid dream yet either, but I'm working at it.
As for SP, that only happens to you by coming out of it because it just doesn't work before you haven't been asleep yet.
Try waking up 3-4 hours later. I think that is the problem, but if anyone has any other answers that would help a lot of us, i am a novice.
