In meditation practice, you might experience a muddy, semiconscious, drifting state, like having a hood over your head: a dreamy dullness. This is really nothing more than a kind of blurred and mindless stagnation. How do you get out of this state? Alert yourself, straighten your back, breathe the stale air out of your lungs, and direct your awareness into clear space to freshen your mind. If you remain in this stagnant state you will not evolve, so whenever this setback arises, clear it again and again. It is important to be as watchful as possible, and to stay as vigilant as you can.
