Yes, failed Wilds generally create DILDS.
Congratulations on your first lucid!
that's the good thing about WILDS, with me happens the same everytime I fail WILD. I think that you DILD then because the last thing about your mind think is "being aware and not fall asleep"
so, I think, why to not try WILD everytime? so you get loads of DILDS =P

bye! congrats again!
