Narrative:
At 9000 ft on a vector, a clearance was received to descend to 2500 ft. The clearance was read back including our tail number and a descent was commenced. At 7000 ft approach asked what we were assigned. He informed us that we were never given that clearance and to descend to 6000 ft now. No loss of separation. The cause may be the stressful situation the pilots and controllers were confronted with. This stress from the surrounding WX may have caused the wrong clearance to be read to us.

Title: FLC OF A CA212 TOOK ANOTHER ACFT'S CLRNC TO DSND AND WAS STOPPED BY APCH CTLR AFTER DSNDING 2000 FT.
Narrative: AT 9000 FT ON A VECTOR, A CLRNC WAS RECEIVED TO DSND TO 2500 FT. THE CLRNC WAS READ BACK INCLUDING OUR TAIL NUMBER AND A DSCNT WAS COMMENCED. AT 7000 FT APCH ASKED WHAT WE WERE ASSIGNED. HE INFORMED US THAT WE WERE NEVER GIVEN THAT CLRNC AND TO DSND TO 6000 FT NOW. NO LOSS OF SEPARATION. THE CAUSE MAY BE THE STRESSFUL SIT THE PLTS AND CTLRS WERE CONFRONTED WITH. THIS STRESS FROM THE SURROUNDING WX MAY HAVE CAUSED THE WRONG CLRNC TO BE READ TO US.
