I think, Sophia, that you might need to consider that there is more to a successful WILD than just laying down, holding still, and waiting. Also, WILD is simply the name for the transition from wake to sleep (and hopefully to dream) without losing waking-life self-awareness. It is really not about the noise (i.e., those flashing lights, that song, etc), which is just stuff you are witnessing on the way to WILD. There are other things.

I suggest you take a moment and look at DV's nice introduction to WILD, if you haven't already. If you are interested (or more ambitious) you could also try my own DVA WILD class, which covers that other stuff you might need to be doing.

And yes, it is a fine idea to close your eyes -- the plan, after all, is to go to sleep, right?
