It depends on what you mean by WILD. If you want to fall asleep consciously at the beginning of the night, this is completely possible (although there will more than likely be no dream at first). The dream will happen later on, if you remain conscious (around an hour or so later, provided that you are actually asleep). If you want to fall directly into a WILD at the beginning of the night, it probably is not going to happen (but it could).

So far as techniques for waking up go, try drinking a glass of water before bed (don't overdo it). Also, if you are having trouble sleeping, minimize the use of electric light and devices 2-3 hours before bed. If you are in the dark, your body will begin to produce melatonin, which will help you fall asleep. Some good stretching, light yoga, or body relaxation is also good.
