Little question on WILD

Well, I'm usually very good at WILDing, and I have multiple per week, usually whenever I want to have them. Recently, I've noticed my luck has been running out, this is what happens:

Right when I get to the vibrations, the WILD discontinues or something. I get passed the vibrations, I'm not lucid, and I feel just as though I've been there the whole time, no SP, nothing. What do I do? Just after the vibrations, nothing else happens. I'm not one to be asking a question like this, but here I am. I would never have thought I would have trouble WILDing, but now I do.

Any suggestions?
