Can people hear what i think?

Ok im a sane person and i dont understand but i believe people can hear my thoughts. Its only causing problems nothing good is coming from it...people respond to what i think and are also angry at what i think..is it possible? Or was something put into my body brain or can it happen just naturally i have been researching online and have found this has happend to alot of people and most answers seem to be just asuming they are paranoid...but im not paranoid or i dont believe i am...can anyone tell me ... Can thoughts be heard?
