I always feel drunk in lucids, I stagger around and often find that my neck muscels don't work after a WILD.

I usually feel weak too, I tried the lucid task of tearing down a building. IRL if I punch the right wall in my house, the house shakes, in the dream, it didn't even make a sound. I couldn't even punch through my window.

Along with feeling weak, I usually feel weightless, in that dream (Above) I just opened the window and kind of drifted out.
