Anxiety: red heels clicking on chequered marble

I associate this one with red high heels clicking on chequered marble. It's not so much a voice but a clicking thumping fear. Heart beat suffocation. Clang clang clang of the prison warden coming to smash my face in. As a kid I’d lie awake with my ears pressed into the pillow listening to my heartbeat. I didn't know it was my heart. It sounded to me like an impressive woman walking stalking determinedly down an endless corridor. I got to thinking they were red high heels she was wearing. Something about danger, power, sex and blood. I got to thinking it was the prison warden wearing those red high heels. She had signed out at the end of her shift, everyone thought she'd gone. She could do anything she wanted. I got to thinking as I lay there listening to the quickening click to the thump thump thump of her red high heels, that when she reached the end of the long corridor she was going to take off her shoes and... but I could never get beyond that point because I was always too focused on breathing, trying to suck in air, dizzily swallowing oxygen, remembering how to breathe. Eyes blurring while my head shrieked in pain probably because she'd reached me with her red high heels.
