im 13 please help me

This really weird thing happens to me. It's like that voice when I'm thinking to myself is warped. Like, monotone sort of. And when I listen to music it sounds weird... like the person isn't trying. It's like the tone is messed up or something. It's so weird. It just happens in goes away in 5 or 10 minutes. I have it right now. I get it about once a month, more or less. ITS SO WEIRD HELP ME!! its annoying to. and really hard to explain, like explaining color to a blind person.
