I'm not new to lucid dreaming, I've had one before and I know a lot about it, but I have a question about the WILD technique.

Can it be done at night? I really can't afford to miss out on even an hour of sleep, and it would really hard to wake up earlier than 4, it's already hard enough.

Can a WILD be done right before I go to sleep? I can handle a challenge, I just thought I would see if anyone's done it before me.
