Thiada, it sounds like what you're experiencing are the hallucinations, which can occur before or during the sleep paralysis stage of a WILD. I would recommend allowing yourself to relax, and don't focus too much on the hallucinations. It's hard to describe because I've only had one WILD, but you should try to just drift into the dream without trying to get there. Whatever you're feeling when you start to experience the hallucinations, feel it more and anchor yourself to what you can see/hear/etc and therefore the dream.
