I suggest doing your next WILD a bit earlier, when you'll have more time to sleep (and when your body will still want more sleep).

I also suggest staying calm when you find the dream materializing around you. Wait a while. Look around and notice how detailed things are. Once the dream feels stable feel free to do whatever. If you find yourself in the dream and you are moving (like in the dream you described) just go with it. But try to stay calm and observant for the first little bit.

Good luck!
