Sounds like you have reached hypnagogic state but not fallen asleep afterwards, maybe you were little bit too awake? You could try doing less active tasks next time or doing attempt little bit earlier, also it indeed does sounds like some progress.
Also don't think about WILDing as about something that is hard, since anything dream related is based on expectations, if you think that it's hard it will be harder than it could have been otherwise, be confident and keep trying, and you'll reach it!
Good luck!
