When I was pooping, I farted, and it sounded like a scream.
A scream? Why do you think it sounded like that?
I'm not sure why it sounded like a scream.
The bathroom is your private place and you should feel okay about letting out a fart while in there. No one should judge you for your bodily functions.
I don't want it to be private. I want to do it again so I can prove to people it sounded like a scream.
That is not okay.  The same privacy that means others shouldn't judge you means that it's not right to force others to listen to your bodily functions. That can gross people out and be disgusting if they don't want to hear it.
