odd stuff, disturbances in the force

this morning i did the stretch routine mostly with my heels off the floor.  to arrange the angles to be able to "relax" into it: within the set parameters there are better ways to do it.  5-8 minutes heels off floor: relax the calves, relax the shins, burn baby burn.  and this time the wiggling fingers put out to the edge of the visual field to therefore pay attention to both sides at the same time.

yesterday in class 2 people got hurt separately, one just doing a forward roll, other did a breakfall wrong i guess, i didn't see it.  first went to hospital, sensei thought broken collarbone, other some problem with a leg.  wanted to slow down & relax more than usual.
there is a spot of time between the demonstration of the technique and the first try that the lesson falls out of the head.  the bow, the finding of the partner, the bow, the entry into the technique, the arrangement of the lesson falls apart & i stand there & have to put it back together if i can.  or, if i've trained enough on it i can go with the training & not think about it.  that empty zone, like a dream, when i got up the dream ended, i can try to piece together the fragments of the memory.  passive active.  how wide is the transition zone between passive & active?  does it perhaps only seem that there is an absolute distinction of off/on?  must investigate further.
