a woman breathing, a gasp, sneezes, scared breaths
a toilet flushing
a metal shovel hitting brick and a metal bucket
hot pan being placed in cold water, sizzle
metal scraping across hard uneven ground, shoveling gravel, sharpening a knife or axe
science fiction radio crackling, electronic sound, alien communication
footsteps on hollow metal coming closer, metal scraping and pressurizing
a key board synthesizer long note, sci-fi laser, science fiction
heeled shoes walking on a wood floor
a long door creaking as it opens and closes
