Hey, welcome to dreamviews!
Sleep paralysis is not a requirement for WILD and there's alot of confusion and misleading about it over internet, check out this thread: http://www.dreamviews.com/wake-initi...mystified.html and sorry that you were going wrong way all the time. For WILD you just need to fall asleep while keeping awareness using an mental anchor, like mantra or counting, also you need to use WBTB or nap, WILDing at usual sleeping time is often unsuccessful unless you are really talented or skilled. Also here's an in-depth tutorial that describes process so be sure to check it out: WILD
Good luck with your WILDs!
