I know what you mean. Just last week I took a nap in Lit. while everybody read a book (I already finished it). Anyway, I fell asleep and apparently did a WILD w/o even trying. Anyway, I had a lucid that lasted about 10 seconds and then had a FA. That only lasted a few seconds to before I literally sat straight up in my desk for no reason wide awake. So...a few thoughts on this:

1. Naps can be quite easy to achieve, at least for me (an ironically it take me about a half-hour to fall asleep at night). Taking little effort on your part, you can have naps throughout the day. Thats controlling your SLEEP.
2. WILDing is a good option in cases such as these. Being in a noisy environment in which your brain maintains a state of high awareness should allow you to slip into a WILD IF you can fall asleep. Trying to hard might mess this up. That's controlling your DREAMS
3. That about answers your questions on controlling "it". Lastly, heres some scientific facts to back up this theory of "Easy WILDs When Napping in Class" : The brain is highly active in our sleep (not just when we dream) and maintains a high alert from our senses. Mainly concerning noise, the brain filters any and all sounds we hear and picks out anything interesting. This is why you can be woken up easily by your name being called or the alarm due to your being familiar with these and "listening" for them. It is also why a loud car or thunder (unless it is lightening right by you) will not wake you up and you sleep soundly throughout the night. This also happens when awake such as picking your name out of someone's conversation. This process of your brain filtering sensory information is based on something known as the Signal Detection Theory. My point is that the brain is doing this more in sleep when you're in a noisy/unstable environment (in other words you sleep "lighter") and your brain is processing the sensory information at a higher rate therefore making your brain slightly more "aware" and possibly leading to a WILD.

FWOO! I seem to have gone off on a tangent. In layman's terms though: It has happened before (the other posts above are testament to this) and it can be controlled to the extent of your falling asleep and having a WILD with more ease than trying at night. Hope I helped.
