I can't guarentee anything, but hissing is usually 'knock it off' and growling is 'fuck off i'll bite.' You could try being generally loud first, though, since your human hiss might not get parsed the same as a cat hiss if you don't do it right at first. Say 'no!' very loud. Clap your hands. If it's far, stomp and go "hey!!!" Some cats pick up weird socialization and I'm not a cat expert, so take what i say with a grain of salt, tho.
When I see my cat scratch the wrong thing I go "Hey!!" and thump the table and she'll stop what she's doing. Then when she scratches the right thing, I go "Oh, good job, kitty!" in a much softer, gentle voice. She doesn't really get it. She hears the loud tone, stops scratching, and jumps up on the couch. She doesn't get it's 'stop,' but she stops, so it's good enough for me. They don't like loud noises or certain smells, so you can use those to make them not want to be around you without hurting them.

I like the advice here on how to reduce a cat phobia. If you spend time with some very chill cats who will only be aggressive in extreme cases, you'll learn their body language and signals and have an easier time signalling to them. It's easier to "get" cats when you understand how little they understand us.
I wish I could help more. I remember being terrified of dogs as a kid, until I met a neighbor's tiny elderly guy, who was so gentle and hard to fear, I slowly overcame it. Good luck! Sorry about the rambling.
Like a dog peeing on the floor, dropping a mouse on the bed has to happen once so they can figure out it's unwanted. Unfortunately. The impulse is sweet, though - she was sharing food and play with me - so it's just a silly story I share about her, now. She was such a great little hunter. I had her as a kitten in an old house, and she leapt to the challenge of taking care of the slight mouse problem. Or, supplementing the household's food, as perhaps she saw it. When we moved from that house to one with a serious mouse problem, she became the hardest worker there. That memory, once the sheets were clean, became a cherished one. She cared about my well being, and giving me food was a way of showing me I was part of her cat family.
