ALT DEV. TURB AND CONFUSION.

Narrative

IT WAS A CLR MORNING WITH A HIGH OVCST. I RECEIVED A CLRNC TO CLB TO 4000 FT AT ZZV. CMH THEN CLRED ME TO 8000 FT. I WAS CONCERNED ABOUT TSTMS AHEAD. MY WX RADAR INDICATED TSTM TO THE SE. CMH RPTED NO WX IN THE AREA. I DECIDED TO TRY A CLB ON TOP OF THE OVCST; AND ASKED CMH FOR A CLB TO 11000 FT. THEY REPLIED THAT 11000 FT WAS THE WRONG WAY FOR DIRECTION. I THEN ASKED FOR AND RECEIVED CLRNC TO CLB TO 10000 FT; KNOWING THAT I WOULD PROBABLY NEED HIGHER. I WAS STILL AT 4 TO 5000 FT BUT THE CEILING LOOKED TO BE AROUND 8000 FT. WHEN I APCHED 10000 FT THE TURB BECAME HEAVY. AT THIS POINT I WAS CONCERNED WITH MANY THINGS THAT WERE GOING ON AROUND ME; AND I WAS HAVING TROUBLE MAINTAINING A SMOOTH CLB. AS I REACHED 10000 FT WE HIT A POCKET OF VERY SEVERE TURB. BOTH MY PAX AND MYSELF HIT THE CEILING OF THE ACFT. I WAS DAZED BY THE BLOW AND MY PAX WAS DELIRIOUS AFTERWARDS. BY THE TIME I HAD REGAINED MY COMPOSURE WE HAD CLBED TO 10600 FT. UPON BEING NOTIFIED BY CMH OF THIS; IMMEDIATELY ASKED AND RECEIVED CLRNC TO DSND TO 4000 FT. ALL THE TIME I WAS VFR. AFTER THE CAT; I DIVIDED MY TIME BTWN FLYING THE AIRPLANE; MY PAX; AND THE TSTM; WHICH NOW LOOKED TO BE DIRECTLY IN PATH TO LOU. BY THE TIME I REACHED 5000 FT MY PAX SEEMED TO BE RECOVERING AND I TURNED MY ATTENTION TO HIM; CMH AT THIS POINT HANDED ME OFF TO DAY. I THEN REALIZED THAT I MAY HAVE LEVELED OFF AT 5000 FT FOR A SHORT PERIOD OF TIME. I CALLED DAY AND CONTINUED MY DSCNT TO 4000 FT. THE REST OF THE FLT WAS UNEVENTFUL. IN RETROSPECT I SHOULD HAVE ABORTED MY ATTEMPT TO CLB ON TOP WHEN I REALIZED THAT I WAS GOING TO HAVE TO GO VERY HIGH TO DO SO. AT FIRST I THOUGHT THAT I COULD ENTER THE OVCST AT 8000 FT AND EXIT BY 11000 FT (HENCE MY CONFUSION ABOUT ALT AND DIRECTION OF FLT). CLBING TO 10000 FT PUT ME JUST UNDER THE OVCST WHICH PROBABLY CAUSED THE TURB.
